This CT abdomen demonstrated an infrarenal saccular abdominal aortic aneurysm. It has a thick and irregular wall with surrounding fat stranding. The body of the aneurysm noted to be abutting the third and fourth part of duodenum. The stomach and duodenal also noted to be significantly distended with fluid These findings are consistent with aorto-duodenal fistula.
Additionally, there is occlusion of the distal abdominal aorta and evidence of a bypass graft (presumably an axillary femoral graft) in the right anterior abdominal wall without opacification, presumably also occluded.
