A 44 year-old male complained of right lower abdominal discomfort and hemorrhoids. He had neither history of abdominal trauma nor abdominal surgery. A pulsatile mass was palpable on rectal digital examination and bruit was heard at right lower abdominal quadrant.
Pelvic computerized tomogram showed an abnormal mass with homogeneous density near the right side of the bladder. The mass was equally enhanced by the contrast medium.
Digital subtraction angiogram revealed the pelvic AVM which originate from right hypogastric artery. Selective angiogram showed many feeding arteries and a dilated vein.
Surgical procedure was performed with transabdominal approach because this AVM was localized. All feeding arteries and aneurysmally dilated vein were completely removed. Post operative course was uneventful.
Follow up arteriogram after the surgery showed no further abnormal arteriovenous connections.
