Priapism is a prolonged penile tumescence or erection unrelated to sexual stimulation that lasts more than 6 h. High-flow priapism is a rare condition usually due to a perineal trauma with the formation of an arterio-cavernosal fistula between a cavernosal artery and the lacunar spaces of the penis. High-flow priapism is usually diagnosed by clinical examination and color Doppler ultrasound, and the gold standard therapeutic management is represented by digital subtraction angiography. We report a case of a young patient with high-flow priapism after a motorcycle blunt perineal trauma, examining in detail the specific color Doppler ultrasound findings, the diagnostic workup and the therapeutic management.
