In a first-of-its-kind for the Karnataka region and among only the 2nd and 3rd such cases treated in India, Manipal Hospital Kanakapura Road has successfully performed surgical repair of ananterior dural tear in 2 patients with decade-long undiagnosed Spinal CSF leaks.

Superior cerebellar artery (SCA) aneurysms are exceptionally rare (~0.2% incidence), and fusiform variants are even rarer. 🧠
For ruptured dissecting distal SCA aneurysms, endovascular parent artery occlusion offers a highly effective treatment with low morbidity. 💡

**🚨 Medical Mystery Solved: The Diagnostic Trap of Superficial Siderosis 🚨**
Have you or a colleague ever reviewed a brain MRI and spotted Superficial Siderosis centered specifically around the **Superior Vermis**? 🧠
Often, this finding triggers a frustrating diagnostic loop. Because there is a significant lack of awareness about this specific presentation in both neurology and radiology, patients are frequently put through rounds of repeated, invasive cerebral and spinal angiograms to find the source of the bleeding.
**Here is the crucial practice-changing pearl:** 🛑 Stop the endless angiograms!
🔎 **INSTEAD: Screen the spine to look for an epidural CSF collection.**
The most common, yet frequently missed, etiology for this specific pattern is a **Chronic Type 1a Spinal CSF Leak (also known as a Duropathy or dural defect)**.
By shifting our focus to the spine and screening for that epidural CSF collection, we can finally give these patients the correct diagnosis and spare them from the physical and emotional toll of unnecessary, repeated testing.
Let’s spread the word, close this knowledge gap, and improve patient care! Share this with your colleagues in radiology and neurology. 🩺💡

Treating the "culprit/vulnerable plaque," not just the "percentage."
Paradoxical carotid stenosis—where the symptomatic side is less severe on imaging than the asymptomatic side—remains a high-risk scenario.
Sequential treatment planned: stabilize the symptomatic lesion first, then address the high-grade contralateral stenosis

Spinal CSF leak: Snapshot

A 4-week ordeal, solved in a single afternoon. ✨AWARENESS POST******
​Imagine being completely bedridden for a month. A severe, crushing headache strikes the moment you stand up, only to completely vanish when you lie flat.

​Recently, we saw a middle-aged patient at Manipal Hospital, Kanakapura Road who was living this exact nightmare. She had been seeking answers for four weeks.

Despite multiple consultations and several MRI scans of her brain and spine that were officially reported as "unremarkable," she was still in agony.

She had been given various misdiagnoses, leaving her and her family feeling helpless.
​But sometimes, "normal" scans just require a closer look. 🧠🔍

​When we reviewed her outside MRIs in our clinic, we spotted the incredibly subtle—but definitive—signs of a spinal CSF (cerebrospinal fluid) leak causing Spontaneous Intracranial Hypotension.

The clues were barely there, but to a trained eye, they told the whole story.
​Because the findings were so clear upon review, we didn't waste any time. In that exact same sitting, we took her into the interventional suite and performed a targeted epidural blood patch to seal the leak.

​The most rewarding part? After a short recovery period lying flat, we asked her to stand up. For the first time in a month, the weight was gone. She walked out of the hospital later that afternoon, completely upright and pain-free. 🚶‍♀️🙌

​Stories like this are a powerful reminder of why we do what we do. An "unremarkable" report shouldn't be the end of the road when a patient is suffering.

Finding those subtle signs can literally give someone their life back!

Thunderclap headache😓
No bleed🩸
But not a benign scan!

A patient presented with a sudden, severe thunderclap headache, yet the initial brain imaging brain🧠showed no intracranial hemorrhage!

In such situations, the absence of bleed does not exclude a dangerous vascular cause, so the next step was to look deeper for the culprit lesion.

Advanced vessel wall imaging with contrast revealed focal aneurysmal wall enhancement in a dissecting vertebral artery aneurysm.
Aneurysm wall enhancement on vessel wall MRI is recognized as a marker associated with aneurysm instability, inflammation, and increased rupture risk.

This was the key clue🔑: when there is no visible hemorrhage, vessel wall imaging can help identify the true source of symptoms and guide timely treatment.

After detailed multidisciplinary evaluation, the lesion was treated with flow diverter stent placement to reconstruct the parent artery and secure the aneurysm.

A reminder that in thunderclap headache, a normal CT does not always mean a normal vessel, and the culprit may only be visible when you look beyond the lumen!

Mastering thalamic vascular variants is crucial in stroke imaging! 🧠 Let's review the 4 patterns of paramedian thalamic supply:

​🔹 Type I: Symmetrical independent arteries (most common normal anatomy)

🔹 Type IIa: Asymmetrical origin from a single PCA

🔹 Type IIb: Artery of Percheron (A single common trunk bifurcating to supply bilateral thalami) ⚠️

🔹 Type III: An arterial arcade pattern connecting the PCAs

​Recognizing the AOP (Type IIb) is critical in the reading room—occlusion means bilateral thalamic infarcts from a single vessel!
