Infected abdominal aortic aneurysm associated with a psoas abscess, aorto-duodenal and sigmoid fistulas. Case report and review of the literature.

A case of atherosclerotic abdominal aortic aneurysm, complicated by aortoenteric fistulizations and infected by Escherichia coli, is presented. Chronic contained rupture resulted in the formation of a huge left psoas abscess which was responsible for the symptoms. No similar case has been reported in the literature. Resection and extra-anatomic vascular reconstruction were curative.
