Appendicitis: an unusual cause of infected abdominal aortic aneurysm.

ABSTRACT

An unusual case of appendicitis, which presented as an infected aortic aneurysm is described. Gas was noted in the wall of the aneurysm on abdominal radiographs and computed tomography, due to the formation of an appendico-aortic fistula. Computed tomography also demonstrated a contained rupture of the aneurysm.
