When imaging points to one bad gland, do you trust it and stop there — or check all four anyway? Surgeons split on this, and the answer shapes everything from operative time to the odds of a missed second gland. Here's how that decision actually gets made in the OR.

How Surgeons Decide Which Parathyroid Glands to Remove

Once a decision for surgery has been made and the surgeon has selected the desired imaging prior to the surgery, what actually takes place during the operation? How does the surgeon determine which gland or glands are abnormal?

The answers to these questions are not quite as straightforward or consistent among surgeons as one might expect. There are a variety of gland characteristics that a surgeon can rely on to decide which glands to remove. These characteristics include:
1. The findings on preoperative imaging
2. The shape, size, and color of the individual glands
3. Comparison of the four glands during the surgery
4. Measurement of PTH drop following removal of one or more glands
5. Pathologic assessment of the gland, either by frozen section (available during the surgery, but adds time) or permanent section (only available a few days after)

In practice, these five inputs tend to sort surgeons into two broad philosophies.

Philosophy 1: Trust the imaging, find the one gland

Some surgeons rely heavily on preoperative imaging to decide if they can select a single gland to locate and remove. These surgeons typically will not recommend surgery unless at least one, and preferably two, preoperative imaging tests point to a single gland as the culprit. Given this selectivity, the operation is focused on finding only one gland presumed to be abnormal.

Once it's identified, the surgeon typically uses intraoperative PTH measurement to see if the level has dropped. If it hasn't dropped enough, the operation is extended to look for the other glands, with PTH rechecked after any additional glands are removed until the level falls sufficiently.

Some surgeons in this camp also send every removed gland for frozen section to confirm it's parathyroid tissue and to get the pathologist's estimate of "hypercellularity." That said, there's no real consensus on whether hypercellularity correlates with PTH overproduction, so it's debatable how useful that feedback actually is, and sometimes the pathologist can't even confirm the tissue is parathyroid gland from the frozen section alone.

The tradeoff: if the preoperative imaging is accurate and the PTH level drops sufficiently, this can be the least invasive approach. But imaging can localize one abnormal gland while missing a second one that doesn't show up and the PTH value might still drop enough to look like a cure even though an abnormal gland remains. Those patients sometimes aren't discovered to have persistent hyperparathyroidism until lab work at six months shows the calcium is still high. And if the PTH doesn't drop after the single gland comes out, relying on intraoperative measurements can significantly prolong the surgery, since each result takes about 20–30 minutes to come back.

There's also a judgment call baked into this approach: what PTH level counts as evidence of cure? Historically, surgeons have accepted a level that's 50% or less of the preoperative value but that criterion can be misleading, especially when the starting PTH was very high.

Philosophy 2: Find all four glands, every time

Other surgeons choose to identify all four glands at the initial operation regardless of what the preoperative imaging showed. The imaging becomes a roadmap rather than a limit; the surgeon incorporates it with what's actually seen at surgery. The glands flagged by sestamibi scan, ultrasound, or other imaging are expected to appear abnormal and are removed; the remaining glands are exposed to confirm they look normal, or "dormant."
Some patients have what's called four-gland hyperplasia, where all four glands are contributing to the hyperparathyroidism to varying degrees. In these patients, all four glands may look similar, each with some abnormality, but not necessarily large. Here the surgeon must identify the most normal-appearing gland, leave a portion of it in place, and remove the other three completely.

Intraoperative PTH measurement isn't routinely needed with this approach, since it's a safe assumption that identifying and removing the abnormal gland(s) from all four will cure the patient. PTH is simply checked later, in recovery or at a follow-up visit.

The tradeoff: this approach doesn't depend on positive preoperative imaging and skips the extra operating-room time for intraoperative PTH. But it's more invasive, since dissection extends to all four glands, which raises the incidence of temporary hypocalcemia (and, rarely, prolonged or permanent hypocalcemia if the "normal" glands' blood supply is compromised during dissection). More extensive dissection also means a higher chance of temporary hoarseness after surgery, though this is almost always transient.

Neither approach is simply right

Both philosophies are defensible, and the best surgeons choose deliberately based on the quality of their imaging, their patient population, and how much operative time they're willing to spend chasing a PTH number. But deciding on a philosophy is only the first challenge. Once you're actually in the neck, you still have to answer a much more concrete question: what does an abnormal gland actually look like? That's the subject of the next post in this series.

How Surgeons Identify an Abnormal Parathyroid Gland—Part 2 of a Series
“Imaging Guides, Experience Decides”

Once the diagnosis of primary hyperparathyroidism has been established from the calcium and PTH levels, and a decision for surgery is made, the next step is usually to determine what additional information should be obtained in order to assure a successful operation.

This is where imaging becomes useful.

It is worth repeating the central point from Part One: imaging does not make the diagnosis. Imaging is performed after the diagnosis has been made to help the surgeon decide where the abnormal gland is likely to be and how best to approach the operation. Even patients with negative imaging remain candidates for surgery if the biochemical diagnosis is clear.

There are several different imaging studies available, and they do not all provide the same information.

1. The sestamibi scan

The sestamibi scan has been one of the most commonly used parathyroid localization studies for many years.
A small amount of radioactive material is injected into the bloodstream. Hyperfunctioning parathyroid tissue often takes up and retains more of the sestamibi than the surrounding tissues. Images are then obtained to look for an area of increased activity.
When the scan shows one convincing focus, it provides useful evidence that a particular gland is hyperfunctioning.
But there are limitations.

A positive sestamibi scan does not prove that the other three glands are normal. It simply tells us that one gland accumulated enough tracer to be seen.

And a negative sestamibi scan does not mean that the patient does not have hyperparathyroidism. It means only that the scan did not localize the abnormal gland. Sestamibi is also less reliable when more than one gland is abnormal.

This distinction is extremely important because I have seen patients whose diagnosis was questioned simply because their sestamibi scan was negative. If the calcium and PTH establish primary hyperparathyroidism, a negative scan does not undo that diagnosis.
If the sestamibi scan is performed immediately before surgery, there can be an additional benefit. The injected sestamibi is still present in the tissues during the operation, allowing the surgeon to use a handheld gamma probe to measure radioactivity. Hyperfunctioning parathyroid tissue usually retains more sestamibi than surrounding tissues, which can help locate an abnormal gland. Once tissue is removed, its radioactivity can also be measured immediately and can provide another clue that the specimen is parathyroid tissue, without waiting for a frozen-section pathology report. I will discuss this technique in more detail later in this series.

2. Ultrasound of the neck

Ultrasound looks at the problem differently.
Rather than measuring the uptake of a radioactive tracer, ultrasound looks directly at the anatomy of the neck. An enlarged parathyroid gland often has a characteristic appearance and may be seen behind or adjacent to the thyroid gland. Normal or dormant glands are rarely seen on ultrasound because they blend in with the other surrounding soft tissues.

Ultrasound has several advantages. There is no radiation, it is relatively inexpensive, and it also gives us useful information about the thyroid gland.

One limitation is that ultrasound is very dependent on the person performing and interpreting the study. It can also have difficulty identifying glands that are very deep, behind the trachea or esophagus, or located somewhere unusual.

When an ultrasound and sestamibi scan both identify the same gland, that gives us considerably more confidence about where the problem is located. These studies are often complementary rather than competing tests.

3. 4D CT scanning

A 4D CT scan provides much more detailed anatomical information.
The term “4D” refers to the fact that the scan looks not only at the three-dimensional anatomy but also at how a suspected parathyroid gland takes up and releases intravenous contrast over time.

This characteristic enhancement pattern can help distinguish abnormal parathyroid tissue from lymph nodes, thyroid tissue, and other structures in the neck.

4D CT can be particularly useful when the ultrasound or sestamibi scan is negative or when the studies disagree. It can also be very helpful for glands in unusual locations. Studies have shown that 4D CT can localize glands that were not seen on traditional imaging.
The tradeoff is greater radiation exposure and the need for intravenous contrast, so it is not necessarily the first test every patient needs.

4. Choline PET imaging

A newer option is fluorocholine PET/CT. Parathyroid tissue has a high rate of cellular membrane activity and can preferentially accumulate radiolabeled choline. This can allow PET imaging to identify very small or difficult-to-localize abnormal glands.
Choline PET it is gradually assuming a greater role when more traditional studies are negative or equivocal, most often in patients who have already had an unsuccessful first operation. Published studies have reported very high localization sensitivity in selected patients. Availability and insurance coverage can be limiting, so it is not currently a routine study for most patients.

5. No imaging test is perfect

This may be the most important point in Part Two.
Every imaging study provides evidence about which gland or glands might be abnormal. None provides absolute proof.
If a sestamibi scan, ultrasound, and 4D CT all point to the same gland, we can be very confident that gland is abnormal. But that still does not prove that the other glands are functioning normally.
Conversely, if every scan is negative, that does not mean there is no abnormal gland.

If the biochemical diagnosis is correct, there is abnormal parathyroid function somewhere.

That is why I think of imaging as creating a road map for the surgeon. Sometimes the map is excellent. Sometimes it is incomplete. And occasionally it points us in the wrong direction.
Ultimately, the surgeon must combine what was learned before the operation with what is found during the operation.
That leads directly to Part Three.

Once the neck is explored, what does an abnormal parathyroid gland actually look like? Is a larger gland always the abnormal one? What does a normal gland look like? And perhaps most interestingly, what happens to the other parathyroid glands when one gland has been overproducing PTH for a long time?
In Part Three, I will discuss the visual appearance of normal, hyperfunctioning, and suppressed—or what I often call “dormant”—parathyroid glands and how those findings help guide surgical decision-making.

How Surgeons Identify an Abnormal Parathyroid Gland

It is extremely important to understand that we do not need imaging to make a diagnosis of primary hyperparathyroidism. The diagnosis is based on the laboratory findings.

Sometimes those findings are very clear, and sometimes they fall into a gray zone.

If the calcium is repeatedly high and the parathyroid hormone level is elevated—or even “normal” when it should be suppressed—primary hyperparathyroidism is usually the explanation. If the calcium is high and the PTH is appropriately suppressed, then the explanation for the high calcium lies elsewhere.

Borderline situations do occur. If the calcium is only high-normal, or the PTH is only modestly elevated, additional laboratory evaluation may be necessary before the diagnosis is certain. There are also uncommon conditions that can mimic primary hyperparathyroidism, so the lab results always need to be interpreted in the context of the whole patient.

This series addresses the situation in which the diagnosis has already been confirmed.

I have written other posts about when surgery should be recommended, but in most cases surgery should at least be considered once the diagnosis is certain based on the lab work. Some physicians still reserve the decision about surgery until after imaging is performed. That is not the ideal way to think about it.

Once the diagnosis is confirmed biochemically, there is abnormal parathyroid function somewhere. The remaining question is which gland—or glands—is responsible.

That distinction is important because imaging does not tell us whether the patient has hyperparathyroidism. It helps us localize the abnormal gland or glands after the diagnosis has already been made.

In this series, I will look at the different ways we try to identify the abnormal gland or glands, including:

sestamibi scanning
ultrasound of the neck
4D CT scanning
choline PET imaging
intraoperative use of the unique autofluorescence characteristics of parathyroid tissue
visual assessment of the glands during surgery
pathology findings
intraoperative functional testing

Each of these provides useful information, but none of them tells the whole story by itself.

Parathyroid surgery came before modern imaging

Surgery for hyperparathyroidism has a long history. The first generally recognized successful parathyroidectomy for primary hyperparathyroidism was performed by Felix Mandl in Vienna in 1925.

At that time, surgeons had none of the imaging studies we use today. They also could not measure intact PTH levels.

They relied heavily on the clinical picture, serum and urinary calcium measurements, skeletal findings, and exclusion of other causes of hypercalcemia.

Without a PTH level, it was much more important to consider all of the other possible explanations for high calcium before proceeding to surgery. That kind of exhaustive work-up is much less commonly necessary today because modern intact PTH testing allows us to determine whether the parathyroid glands are responding appropriately to the calcium level.

Once the surgeon was confident in the diagnosis, the traditional operation was a bilateral neck exploration. The surgeon would identify all four parathyroid glands and visually decide which gland—or glands—appeared abnormal.

Surgeons relied heavily on the size, color, shape, and appearance of the glands, often supplemented by pathology to confirm that tissue removed was parathyroid tissue.

Large cervical incisions were already routine for thyroid surgery, which made up much of neck surgery at the time, so parathyroid operations were generally performed through a similar exposure.

Fortunately, much of that is now history.

Modern localization studies have allowed surgeons to plan much more focused operations in many patients. But they have also created a new source of confusion: patients and even physicians sometimes begin to think that the scan makes the diagnosis.

It does not.

The lab work makes the diagnosis. The imaging helps us decide where to look.

In Part Two, I will review the preoperative imaging studies available today and explain what each one can—and cannot—tell us about which parathyroid gland is abnormal. Not all surgeons use these studies in the same way, and a positive or negative scan does not always mean what patients assume it means.

Why Would My Doctor Watch High Calcium Instead of Referring Me for Surgery?

Patients are often surprised when a blood test repeatedly shows a high calcium level and the response is simply, “Let’s keep an eye on it.” Sometimes that is reasonable. Sometimes it is not.

The first question is whether the high calcium has been fully evaluated. A mildly elevated calcium level can occasionally be related to dehydration, medications, or another medical problem. But if the calcium remains elevated, the next important step is usually to check the parathyroid hormone level (PTH). If the calcium is high and the PTH is also high, or “inappropriately normal” when it should be suppressed, that strongly supports a diagnosis of primary hyperparathyroidism.

Once primary hyperparathyroidism is established, the discussion changes. The question is no longer simply, “Why is my calcium high?” It becomes, “What should we do about it?”

Why might a doctor continue to watch it?

One reason is that the calcium elevation may be mild and the patient may appear to have few complications. Historically, many patients with so-called “asymptomatic” primary hyperparathyroidism were observed rather than referred directly for surgery. Current guidelines still allow observation in selected patients, but they also emphasize that parathyroidectomy is the only definitive cure and should be considered for most patients with established disease.

Another reason is that the doctor may want more information first. Kidney function, a history of kidney stones, bone density, vitamin D levels, and sometimes a 24-hour urine calcium can help determine whether the disease has already begun affecting the bones or kidneys. These findings can make the argument for surgery even stronger.

There is also a tendency to focus heavily on the calcium number itself. A calcium of 10.3 or 10.5 may not look very impressive on a laboratory report. But the important issue is not simply how far above normal the number is. Persistent hypercalcemia with an unsuppressed PTH represents a real disease process, and even patients without dramatic kidney or bone findings may have fatigue, brain fog, weakness, aches, or other symptoms that affect quality of life.

Sometimes the diagnosis simply has not been recognized
Primary hyperparathyroidism can be easy to overlook because the calcium elevation is often modest and the PTH may fall within the laboratory’s stated “normal” range. But a mid or high normal PTH is not normal when the calcium is high. The parathyroid glands should be suppressing PTH production. That biochemical relationship is often more important than whether either individual number is dramatically abnormal.

This is one reason patients may have elevated calcium documented for months or even years before someone connects it with the parathyroid glands.

When should surgery enter the conversation?

Certainly when there are kidney stones, declining kidney function, osteoporosis, fractures, or more significant hypercalcemia. These are well-established reasons to recommend parathyroidectomy. But surgery should not necessarily be reserved only for patients who have already developed complications. The American Association of Endocrine Surgeons states that parathyroidectomy is indicated for symptomatic patients and should be considered for most asymptomatic patients as well.

Symptoms also matter. A patient who is tired, foggy, weak, or generally feels poorly may have a very different reason to pursue treatment than someone who truly feels well. Those symptoms are difficult to measure, but that does not make them irrelevant.
And the operation itself should be part of the equation. In the hands of an experienced parathyroid surgeon, parathyroid surgery can often be performed as an outpatient procedure, with a high likelihood of cure and a very low risk of complications. That changes the balance when considering years of continued observation versus definitive treatment. High-volume surgical experience is associated with better outcomes in parathyroid surgery.

So is watching high calcium ever reasonable?

Yes. A patient with very mild disease, no meaningful symptoms, normal kidney function, no kidney stones, satisfactory bone density, and stable calcium levels may reasonably choose careful observation. But watching should be an active decision, not simply the absence of a referral. It should include periodic calcium testing, assessment of kidney function, and monitoring of bone health.
The more important question may therefore be:
“Has my high calcium been fully evaluated, and have I had a meaningful discussion about whether surgery is appropriate?”
If the answer is no, it may be reasonable to ask for further evaluation or a consultation with someone experienced in primary hyperparathyroidism.

Is There a “Wait and See” Role in Hyperparathyroidism?

In most patients with primary hyperparathyroidism, surgery is the treatment that should be considered first. It is the only treatment that actually cures the problem. Once the diagnosis is clear, the main question is usually not whether anything should be done, but whether there is a good reason not to proceed with surgery right away.

Primary hyperparathyroidism is a biochemical diagnosis. If the calcium is high and the parathyroid hormone level is also high, or “inappropriately normal” when it should be suppressed, that establishes the diagnosis. At that point, the discussion usually turns to management.

The reason surgery is the default option is straightforward. Primary hyperparathyroidism is not just a lab abnormality. It can affect energy level, concentration, bones, kidneys, and overall quality of life. Some patients already have kidney stones, reduced bone density, or other measurable effects of the disease. Others do not have dramatic findings, but they still feel tired, foggy, weak, achy, or just not quite right. In either situation, surgery is the one treatment that can actually correct the underlying problem. In the hands of an experienced parathyroid surgeon, surgery can usually be done as an outpatient procedure, with a high likelihood of success and a very low risk of complications.

This is also why it is important not to minimize the diagnosis just because the calcium is “only a little high.” Mild hypercalcemia can still reflect a real parathyroid problem. In many patients, the diagnosis and the recommendation for surgery are already clear from the lab work and the overall clinical picture.

That said, there can be a wait-and-see role in selected patients. But think of it as a qualified exception, not the starting point. A patient might be a reasonable candidate for observation if the calcium elevation is mild, kidney function is preserved, there is no history of kidney stones, bone density is normal or near normal, and the patient is not having significant symptoms that seem attributable to the disease. Even then, observation is not the same as doing nothing. There should be a deliberate plan for follow-up.
That follow-up usually includes repeat calcium testing, monitoring kidney function, and periodic bone density evaluation. The purpose is to watch for evidence that the disease is progressing or beginning to affect the kidneys or bones. If that happens, the argument for surgery becomes stronger.

So is there a “wait and see” role in hyperparathyroidism? Yes, for some patients. But in most cases, the more appropriate way to think about it is that surgery is the primary treatment, and observation is an option that may be reasonable only when the overall picture is favorable and careful follow-up is in place.

Why Am I So Tired? One Common Cause Patients Miss

Feeling tired all the time is one of the most common complaints patients bring to the doctor. The problem is that fatigue can come from almost anything. Stress, poor sleep, aging, medications, thyroid problems, anemia, depression, and dozens of other issues can all play a role. But there is one cause many patients do not know about: high calcium from primary hyperparathyroidism.

Fatigue and weakness are recognized symptoms of primary hyperparathyroidism, even though the condition is often first found on routine blood work rather than because of dramatic symptoms.
Primary hyperparathyroidism occurs when one or more parathyroid glands are overactive and produce too much parathyroid hormone, or PTH. That causes the calcium level in the blood to rise. Some patients develop classic problems like kidney stones or osteoporosis, but many do not. Instead, they just feel worn down, foggy, achy, weak, or not quite themselves. Fatigue may be one of the earliest or most overlooked clues.

The challenge is that fatigue is a subjective symptom. There is no scan or single questionnaire that proves high calcium is the reason a person feels drained. That said, the symptom still matters. In real practice. Many patients with hyperparathyroidism report low energy, poor concentration, and a general sense that something is off. Recent data and surgical guidance have increasingly acknowledged that neurocognitive and quality-of-life symptoms can be part of the disease, even if not every guideline uses them as a strict stand-alone indication in the same way as kidney stones or osteoporosis.
So how do you know whether fatigue could be due to a parathyroid problem? The first step is not a scan. It is the lab work. If the calcium is high and the PTH level is also high, or “inappropriately normal” when it should be low, that supports a diagnosis of primary hyperparathyroidism. If the calcium is high and the PTH is suppressed, then the parathyroid glands are acting normally and another cause of the high calcium should be considered. The diagnosis is biochemical. Imaging is used later to help plan surgery, not to make the diagnosis.

It is also important to be realistic. Not every tired patient has hyperparathyroidism, and not every patient with hyperparathyroidism is tired because of it. But when a patient has persistent fatigue along with high calcium, that possibility should not be brushed aside. In some patients, the lab findings and the symptom pattern fit together very well.

If primary hyperparathyroidism is identified in the setting of fatigue that is otherwise unexplained, surgery is a clear choice in most cases. In addition, it is appropriate to determine whether it may already be affecting the patient’s life, kidneys, bones, or overall well-being. Surgery is the only definitive cure for primary hyperparathyroidism. And the good news is that many patients with fatigue due to primary hyperparathyroidism have significant improvement in their symptoms after surgery.

The bottom line is simple: if you are tired all the time and your calcium is high, do not assume it is unrelated. Fatigue is common, but one cause patients often miss is primary hyperparathyroidism. Sometimes the answer is as simple as a routine blood test.

What Tests Do I Really Need Before I Decide on Parathyroid Surgery?

Patients often ask this question after they learn their calcium is high. That is the right question. The answer is that the decision almost always starts with the lab work, but it should also include the patient’s symptoms and any signs that the disease may already be affecting the kidneys, bones, or other organs. Primary hyperparathyroidism is fundamentally a biochemical diagnosis. Imaging and additional studies can be helpful, but they do not make the diagnosis.

1. The most important tests are the calcium and PTH levels.
In most cases, the key decision point comes from the blood work. If the calcium is high and the parathyroid hormone level is also high, or “inappropriately normal” when it should be suppressed, that is the central evidence for primary hyperparathyroidism. In many patients, those labs already make the diagnosis clear enough that surgery can be discussed seriously right away. The scan does not make that decision. The blood work does. You will note that ultrasounds and Sestamibi scans are not even mentioned in this article. These scans really are only utilized in planning an operation and need not be done prior to that.

2. Symptoms matter, even when they are subjective.

Not every patient presents with kidney stones or obvious osteoporosis. Many patients come in because they feel tired, foggy, run down, achy, anxious, or just not quite themselves. These symptoms are not always easy to measure, but they are still part of the decision-making. They often fit with what we see in patients with hyperparathyroidism. When the lab findings are convincing and the patient is having symptoms that may reasonably be related to high calcium, that often strengthens the case for surgery even if no other test has yet been done. Current guidelines note that neurocognitive and quality-of-life symptoms are recognized clinically, even though they are not always used as strict formal criteria the same way kidney or bone findings are.

3. Additional testing can show whether the disease is already affecting the body.

Once the diagnosis looks likely, the next question is whether the hyperparathyroidism may already be causing systemic problems. That is where tests such as kidney function, kidney imaging, 24-hour urine calcium, and bone density can become useful. A history of kidney stones, silent stones seen on imaging, reduced kidney function, or bone loss on DEXA all strengthen the argument that the disease is not just a lab abnormality. These findings are well-established reasons to recommend surgery.

4. In most patients, these extra tests do not determine whether surgery is needed. They help show how far the disease has progressed.

This is an important practical point. In many patients, the calcium and PTH pattern is already convincing enough, and the overall picture already supports surgery without waiting for a 24-hour urine calcium or a bone density test. Those tests are still worthwhile because they can document whether there has already been progression to kidney or bone involvement. But in most straightforward cases, they do not change the overall recommendation for surgery. They add information, more than changing the basic conclusion.

5. Borderline cases are where the extra testing can matter most.
When the labs are only mildly abnormal, the additional studies can help move the decision one way or the other. For example, a patient with only modest calcium elevation but a history of kidney stones and high urinary calcium may look very different once that full picture is known. Likewise, a patient with borderline lab findings who already shows osteopenia or osteoporosis on DEXA may have a stronger reason to move toward surgery sooner rather than later. Current guidance includes renal stones, hypercalciuria, osteoporosis, vertebral fracture, and reduced kidney function among the findings that can support operative management.

In Summary

So what tests do you really need before deciding on parathyroid surgery? First, you need the right lab evaluation to establish whether the high calcium is truly coming from a parathyroid problem. After that, the decision is supported by the patient’s symptoms and by whether there is evidence that the disease is already affecting the kidneys or bones. In many cases, the diagnosis and the recommendation for surgery are already fairly clear from the labs and the overall clinical picture. Additional testing is often helpful, but it is most valuable for showing the impact of the disease and for clarifying borderline situations.
