High Flow Priapism on ¹⁸FDG PET/CT in a Patient with Urothelial Carcinoma: Case Report

Abstract

We studied a 52-year-old man diagnosed with a high-grade urothelial carcinoma of the upper urinary tract treated with nephroureterectomy and chemotherapy who presented a benign high-flow priapism with intensive 18F-fluorodeoxyglucose (FDG) uptake as an unusual finding in the positron emission tomography (PET)/computed tomography (CT) that also showed mediastinal and lumbo-aortic node involvement and liver metastases. Upon examination, the patient had a painless erection that lasted for five days with no episode of recurrence at two-month follow-up.
