A 71-year-old man underwent 18F-FDG and 68Ga-FAPI-46 PET/CT for initial staging prior to surgery of a squamous cell carcinoma of the lower esophagus under the prospective study NCT04147494. Both scans showed increased uptake in the mid and distal esophagus without evidence of metastatic disease. A soft tissue right infrascapular mass with mild 18F-FDG and moderate 68Ga-FAPI-46 uptake was incidentally found. The patient underwent robotic-assisted Ivor-Lewis esophagectomy and excision of the right infrascapular mass. Histopathology of the right chest wall mass confirmed the diagnosis of elastofibroma.

Emphysematous cystitis is a rare, but severe infection of the urinary tract which is mostly found in older women with uncontrolled diabetes. A 34-year-old non-diabetic male with a past medical history of refractory hepatic encephalopathy presented with fever and increased lower abdominal pain for 1 day. Computed tomography (CT) scan demonstrated multiple gas foci in a diffuse collection of gas within the thickened bladder wall suggestive of emphysematous cystitis, and urine culture revealed Klebsiella pneumoniae as the causative agent. The infection resolved with bladder drainage and irrigation and antibiotic therapy in 1 week. An atypical case of emphysematous cystitis in a young non-diabetic man is reported. Early diagnosis and prompt treatment are essential to achieving a favorable prognosis and to preventing a potentially fatal condition.

A 3-year-old, previously healthy girl started having clusters of seizures, not responsive to multiple antiepileptic medications. High-dose prednisone and intravenous immunoglobulin could partially control the seizures. Lumbar puncture and CT were normal. An MRI showed right hemispheric injury and atrophy compatible with clinical suspicion of Rasmussen encephalitis. Neurological 18F-FDG PET/CT demonstrated asymmetric hypermetabolic activity in the right frontal and parietal lobes compatible with active inflammation. The patient underwent a right functional hemispherectomy, which confirmed clinical suspicion of Rasmussen encephalitis. During the follow-up, the patient has continued to take phenobarbital and levetiracetam (Keppra), with no recurrence of seizures.
