Abstract

[Extract] Arteriovenous malformations (AVMs) are congenital or acquired (trauma, iatrogenic) abnormalities where blood is shunted between the arterial and venous systems bypassing capillaries. They are usually located in the brain, lungs and kidney. AVMs confined to the pelvis are rare, and twice as uncommon in males.

Pelvic AVMs can be incidental findings, but are usually diagnosed during symptomatic workup. Symptoms vary from mild to severe, and can be isolated solitary versus a constellation of symptoms. These includes pain, haematuria and hematospermia and can also be the cause of peri-operative bleeding. Pelvic AVMs may be identified as an isolated pelvic mass lesion or can be seen surrounding soft tissue structures such as bladder and bowel. There are only a few literature reports that describe periprostatic AVMs. We report a 60-year-old man with congenital periprostatic pelvic AVM presenting with isolated pelvic pain treated by endovascular embolization.
