Congenital pelvic arteriovenous malformation with massive prostatic hemorrhage: a case report.

Congenital arteriovenous malformations in the true pelvis are extremely rare: only 7 cases have been described in male patients. We report on a patient who presented with massive hemorrhage after transrectal prostatic biopsy and transurethral resection of the prostate. Diagnosis was established by means of magnetic resonance imaging and confirmed by arteriography. Our attempt at management by embolization and subsequent surgical ligation is described. A literature review and discussion of arteriovenous anomalies are presented.
