Bleeding scrotal arteriovenous malformation.

Background: Arteriovenous malformation (AVM) of the scrotum has, to our knowledge, been reported fewer than 10 times in the medical literature. It may be of congenital or post-traumatic etiology and has been reported to present with spontaneous bleeding.

Case Report: A case of a spontaneously bleeding scrotal AVM that developed after remote trauma is presented. The differential diagnosis of a scrotal vascular lesion includes varicocele, hemangioma, lymphangioma, and AVM. Although ultrasound and magnetic resonance imaging play an important role in the evaluation, angiography is essential to fully delineate the feeder vessels, vascular takeoffs, and draining veins.

Conclusion: Scrotal AVMs are rare vascular scrotal lesions that may present with scrotal enlargement and a bruit. Definitive therapy should be planned in concert with Interventional Radiology and surgical consultants.
