Inferior mesenteric artery aneurysm.

Abstract

This case reports a very large inferior mesenteric artery aneurysm and highlights the importance of proper preoperative arteriography in the patients work-up. In addition the case demonstrates an anomalous arterial supply to the gastrointestinal tract from a dilated inferior mesenteric artery which due to occlusion of the superior mesenteric artery and coeliac axis may have been instrumental in the development of this aneurysm.
