A Case of Internal Iliac Artery Aneurysm as a Fatal Cause Resulting in Acute Urinary Retention

ABSTRACT

Internal iliac artery aneurysm (IIAA) is a type of abdominal aneurysm that is a rare cause of lower urinary tract symptoms because of its anatomic location. If diagnosed after rupture, it can be lethal and surgery is mandatory. A 57-year-old male presented with acute urinary retention and syncope. An intra-abdominal mass initially thought to be an aneurysm was apparent by ultrasound. A computed tomography scan of the abdomen confirmed an internal iliac artery aneurysm accompanied by rupture. The patient was discharged without any complications within 20 days after receiving a vascular graft and resection of the aneurysm.
