title: Forced diuresis (18)F-fluorodeoxyglucose positron emission tomography/contrast enhanced in detection of carcinoma of urinary bladder diverticulum.
abstract: Urinary bladder diverticular carcinomas are uncommon with a lesser incidence of 0.8-10% and its diagnosis still remains a challenge. Cystoscopy is the most reliable method, but evaluating diverticulum with narrow orifices is difficult. Before the initiation of appropriate treatment, proper detection of bladder diverticular carcinoma and its locoregional and distant sites of involvement is necessary. Here, we present a case of 48-year-old male with urinary bladder diverticular carcinoma detected by forced diuretic (18)F-fluorodeoxyglucose positron emission tomography/computerized tomography ((18)F-FDG PET/CT). This case also highlights the significance of forced diuretic (18)F-FDG PET/CT in the detection, staging, and response evaluation of bladder diverticular carcinoma.
