🔎 READ WITH ME | Ectopic Parathyroid

🗓 58-year-old female with prior right thyroid lobectomy for parathyroid adenoma and persistent elevated PTH. ☢️ Dual-phase sestamibi SPECT/CT: thyroid washes out, lesion persists → right paraesophageal adenoma at the thoracic inlet (~1.8 cm).

💧 READ WITH ME | Dynamic Renogram
14-year-old with incidental unilateral hydronephrosis and cortical thinning. Diuretic renogram shows delayed extraction (Tmax 14 min) with >50% activity fall post-Lasix → good drainage = not obstructed.
Take-home: Hydronephrosis ≠ obstruction.
Swipe the curves & drop your call: obstructed or not—and why?

☢️ D4/jejunal adenocarcinoma ☢️ FDG PET/CT shows hypermetabolic duodenal D4/proximal jejunum focal asymmetrical concentric mass like thickening with subsequent luminal narrowing. There is nodular infiltration and stranding of the regional fat planes. There are associated regional prominent sized and rounded lymph nodes.
🗓 Small bowel adenocarcinoma is a rare malignancy (

☢️ Bipartate patella ☢️ well corticated accessory ossification center at the superolateral patellar pole, separated from the main patella by a smooth, lucent synchondrosis. No cortical discontinuity, sharp fracture line, or adjacent periosteal reaction. The margins of both fragments are rounded and sclerotic.
🗓 A bipartite patella is a normal developmental variant in which the patella is formed from two separate ossification centers that fail to fuse, most commonly at the superolateral aspect. The accessory fragment is well corticated with smooth, rounded margins, helping to distinguish it from an acute patellar fracture, which shows sharp, irregular lines and bone marrow edema on MR. Most cases are asymptomatic and discovered incidentally, but pain can occur if there is stress or inflammation at the synchondrosis between the main patella and the fragment.

🫀 SPECT Myocardial Perfusion Case

🗓 Stress-rest SPECT/CT shows a large, partially reversible perfusion defect in the inferior and inferolateral walls (base to apex), with normal perfusion elsewhere.
📊 SSS: 15 | SRS: 5 | SDS: 8 | TPD: 14%
Gated images show hypokinesia in the inferior and septal regions with normal LV function (LVEF: 50%).

📝 Interpretation:
✅ Significant partially reversible stress-induced ischemia
✅ Septal wall abnormal motion, possible obscured ischemia
✅ Normal systolic function

☢️ Moving Meckel ☢️ in a 25-year-old male with history of painless re**al bleeding for the past 1 year. Scintigraphy reveals a focal area of intense tracer uptake in the RLQ appearing at the same time as the stomach with similar intensity, and moving upwards. The SPECT/CT images demonstrate tracer accumulation in blind-ending tubular structure in the right abdomen. Surgery confirmed Meckel’s diverticulum.
🗓️ Meckel diverticulum is the failure of the omphalomesenteric duct to close at its junction with the ilium. Occurs in 2% of the population, if symptomatic usually present by age of 2 years, within 2 feet of the iliocecal valve and 2 inches in length. Complications occur in 20% including painless bleeding (most common), intussusception, bowel obstruction, volvulus, diverticulitis. Movement in Meckel’s diverticulum in scintigraphy can be due to long pouch diverticulum, mobile long mesentery, peristalsis.

☢️ Pulmonary SCC ☢️ Hypermetabolic transfissural right pulmonary well defined soft tissue mass of intense FDG uptake [SUVmax= 12] with spiculated margins and air bronchograms occupying the posterior segment of upper lobe and superior segment of lower lobe measuring 5.3 cm in the maximum dimension. There is surrounding ground glass, nodular opacities and subsegmental atelectasis tracking to the pleural surface without FDG uptake. Hypermetabolic right hilar station 10R lymph nodes of intense FDG uptake [SUVmax= 9], the largest measures approximately 1.9X1.8 cm. Suggested TNM staging T3N1Mx.

☢️ Intervertebral osteochondrosis ☢️ SPECT/CT delayed imaged shows abnormally intense tracer uptake involving L5/S1 disc space narrowing and vacuum phenomenon, endplates irregular erosion and subchondral sclerosis, features of intervertebral osteochondrosis. The initial dynamic scan and immediate blood pool phase that followed showed minimal vascularity and tissue perfusion in the lumbosacral region.
🗓 Intervertebral osteochondrosis is a degenerative process involving the spine affecting the vertebral disc spaces and corresponding endplates. Radiological features include disc space narrowing and degeneration, disc fissuring, endplate erosions, and osteophytosis. SPECT/CT is a valuable modality in identifying pain generators in patients with low back pain.
