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.
