☢️ SPECT/CT: Intense uptake in osteosclerosis and involucrum.
Lucent tracts extending to defects with the involucrum = cloacae.
Cold, dense fragment within cystic cavities = sequestrum.

✅ Final diagnosis: Chronic osteomyelitis.

☢️ SPECT/CT MPI: Irreversible, large sized (4 segments) perfusion abnormality of moderate intensity located in the inferior and inferolateral walls.

✅ Diagnosis: Non transmural MI.

☢️ SPECT/CT: diffuse perfusion and delayed tracer uptake in acetabular zones (I, II, III) osteolysis, subcortical sclerosis, periosteal reaction.

✅ Diagnosis: septic loosening of acetabular component.

☢️ FDG PET/CT: irregular retroareolar soft tissue mass of intense FDG uptake and spiculated margins, typical appearance of IDCa.

✅ Diagnosis: IDCa (NOS) ER+, PR+, HER2- (Luminal A).

☢️ SPECT/CT: well defined ovoid subperiosteal lesion along the lateral cortex of the right 2nd MC diaphysis. cortical mild tracer uptake suggestive of active regional bone remodeling.

✅ Diagnosis: Periosteal chondroma.

☢️ FDG PET/CT: left lung subpleural oval shaped mass like consolidation without significant FDG uptake with indwelling of pulmonary vasculature.

✅ Diagnosis: Rounded atelectasis.

☢️ SPECT/CT: intense uptake in acetabular roof fracture with callus formation, and greater trochanteric (Vancouver type A) fracture.

✅ Diagnosis: Periprosthetic acetabular and greater trochanteric fractures. #MedSky #RadSky #Nucmed

☢️ PET/CT scan shows a rounded tubular structure adjacent to the aortic arch coursing inferiorly anterior to the left hilum draining into the coronary sinus.

✅ Persistent left SVC.

A 32-year-old patient underwent FDG PET/CT, showing a well-defined mass in the right anterior mediastinum with intense FDG uptake (SUVmax= 8.5), smooth lobulated margins, and internal low-density necrotic regions. There was no vascular invasion, and mediastinal planes were intact. #medsky #radsky
