☢️ Tailgut cyst ☢️ Male patient with treated cecal adenocarcinoma, PET/CT scan shows a large well demarcated and noncalcified retrorectal cystic mass with fluid attenuation in the ischioanal fossa displacing the re**um to the left side, surgical resection proved a squamous epithelium lined mass with mucinous content.
🗓 Tailgut duplication cysts are mostly discovered incidentally with female predilection. They can occur at any age but usually after 30 years of age. They are congenital lesions that arise from the primitive hindgut in the true embryonic tail which fail to regress during gestation.

☢️ Lumbosacral transitional vertebra & spondylosis ☢️ SPECT/CT images show bilateral L4 complete pars fractures corresponding to intense perfusion and delayed tracer uptake with sclerosis at the fracture margins. There is no associated spondylolistheses. There is pseudoarticulation of enlarged left L5 transverse process with the aspect of the lumbosacral transitional vertebra, corresponding to intense perfusion and delayed tracer uptake.
🗓 A pars fracture is a stress injury of the pars interarticularis, most often related to repetitive lumbar extension and rotation. It commonly affects adolescent athletes and active young adults, especially in sports such as football, gymnastics, cricket, weightlifting, and dance. Most pars defects occur at L5, followed by L4. They may be unilateral or bilateral. Bilateral defects can progress to isthmic spondylolisthesis, but a pars fracture can be symptomatic even without vertebral slip. Bertolotti syndrome refers to low back pain caused by a lumbosacral transitional vertebra, where an enlarged transverse process forms an abnormal articulation or fusion with the sacrum or ilium. The transitional vertebra itself is common, but it becomes clinically relevant when the pseudoarticulation becomes mechanically overloaded and metabolically active.

🧬 READ WITH ME | FDG PET/CT scan

🗓 52-year-old male with history of squamous cell carcinoma following cervical lymph node biopsy.

☢️ Findings:

🎯FDG avid right nasopharyngeal subtle asymmetrical soft tissue fullness.
🎯FDG avid multilevel bilateral cervical lymph nodes.
🎯FDG avid marrow and sclerotic deposits.


🧬 READ WITH ME | FDG PET/CT scan

🗓 52-year-old male with history of squamous cell carcinoma following cervical lymph node biopsy.

☢️ Findings:

🎯FDG avid right nasopharyngeal subtle asymmetrical soft tissue fullness.
🎯FDG avid multilevel bilateral cervical lymph nodes.
🎯FDG avid marrow and sclerotic deposits.


☢️ Subtle asymmetrical soft tissue fullness, with obliteration of the pharyngeal recess. The left pharyngeal recess appears patent. The Eustachian tube opening on both sides is patent.

☢️ Bilateral Levels I and II variable sized FDG avid lymph nodes.

☢️ The largest FDG avid lymph node in level IIa, located posterior to the right submandibular gland.

☢️ Level IV right cervical FDG avid enlarged lymph node.

☢️ Tibial stress fracture ☢️ SPECT/CT images show left proximal tibial diaphysis posteromedial cortex longitudinal lucent line corresponding to intense tracer uptake, with periosteal reaction, consistent with stress fracture.
🗓 A tibial stress fracture is a fatigue injury caused by repetitive loading that exceeds bone remodeling capacity. The most common site is the posteromedial mid to distal tibial shaft. This is usually a low risk compression side injury.
The important high risk site is the anterior tibial cortex, where delayed union and nonunion are more common.

☢️ Thyrothymic parathyroid adenoma ☢️ 47-year-old female with inconclusive previous parathyroid scan. Planar imaging showed a barely visible uptake in the mediastinal region, SPECT/CT showed a subcentimetric pretracheal oval shaped soft tissue density with mild MIBI retention, surgical resection confirmed thyrothymic ligament parathyroid adenoma.
🗓 The incidence of ectopic parathyroid adenomas is around 5-15%. Most frequently found in the anterior mediastinum. Ectopic inferior parathyroid adenomas can be found in the thyroid, in the thyrothymic ligament, and in the anterior mediastinum, where as ectopic superior parathyroid adenomas can be in the carotid sheath, intrathyroidal, in the tracheoesophageal groove, retro or paraesophageal, in the posterosuperior mediastinum.

☢️ 18F-PSMA PET/CT ☢️ scan demonstrates right abdominopelvic greater momentum ground glass and nodular soft tissue densities of low to high PSMA expression (SUVmax= 17.7) extending as an infiltrative soft tissue density into a left inguinal hernia. Enlarged right external iliac lymph node of high PSMA expression [causing mass effect on the adjacent ureter with subsequent dilatation and hydronephrosis. Biopsy revealed metastatic prostate adenocarcinoma.
🗓️ Prostate adenocarcinoma rarely metastasizes to the peritoneum, but when it occurs, it signifies advanced, aggressive disease with a poor prognosis. Peritoneal metastases from prostate cancer typically arise in the context of widespread disease, often after the cancer has spread to more common sites. Prostate-specific antigen (PSA) levels are often elevated, but the diagnosis of peritoneal metastases may require histopathological confirmation through biopsy.
