Internal Iliac Pseudoaneurysm Rupture Attributed to Perforated Hartmann’s Pouch Diagnosed on CT

Abstract

Rupture is a rare but disastrous complication of an arterial aneurysm. Intraabdominal abscess in association with iliac artery aneurysm is uncommon but can predispose to aneurysm rupture. We report the Computed Tomography (CT) findings of an internal iliac artery pseudoaneurysm formed by a pelvic abscess attributed to the perforation of the patient's Hartmann's pouch. Rupture of the pseudoaneurysm resulted in the patient's death.
