We present benign high-flow priapism with intensive 18F-FDG uptake as an unusual finding in a case of testicular teratocarcinoma with a history of left orchiectomy and chemotherapy. 18F-FDG PET/CT scan showed pulmonary metastases, left obturator node involvement, and intense 18F-FDG uptake in the penis. Upon examination, the patient had a painless erection that lasted for couple of days. Because of pulmonary metastases, second-line chemotherapy regimen was started by his physician. The patient's priapism resolved spontaneously, with no episode of recurrence at 2 years' follow-up.
