Magnetic resonance imaging of partial segmental priapism (segmental thrombosis of corpus cavernosum)

Partial segment priapism or segmental thrombosis of the corpus cavernosum is a rare urologic condition reported 23 times in the world literature. We present the clinical and radiologic findings of a 22-year-old man who presented 7 days after the onset of symptoms in whom the diagnosis was confirmed with magnetic resonance imaging. He was treated conservatively with a nonsteroidal anti-inflammatory drug and aspirin with full restoration of erectile function. On the basis of previous reports and our own experience, we suggest that the management of partial segment priapism should include diagnosis with magnetic resonance imaging and conservative treatment with analgesics and an anti-inflammatory drug to control symptoms.
