RESUMO
ABSTRACT: A 79-year-old man with nasopharyngeal cancer (NPC) presented with diplopia symptom and a history of diabetes mellitus was referred for an FDG PET/CT scan to determine the pretreatment staging. The FDG PET/CT scan revealed NPC with skull base invasion and decreased FDG uptake at the left striatum. A review of his clinical history and a brain MRI conducted 5 months ago confirmed a previous diagnosis of left hyperglycemic hemichorea. In this NPC patient with inadequate blood sugar control, unilateral striatum hypometabolism may persist for up to 5 months after the initial clinical symptoms.

ABSTRACT: A 58-year-old man with lung cancer was referred for an 18 F-FDG PET/CT scan for pretreatment staging. The FDG PET/CT scan revealed focal uptakes in the lower abdomen. We differentiated the etiology of the lesions by performing a delayed scan with urine retention and bladder distension. The delayed scan demonstrated a tubular, radioactivity-filled structure arising above the urinary bladder. Combining the FDG PET/CT scan, clinical findings, and ultrasonography, we made the diagnosis of vesicourachal diverticulum.
