A case of post stenotic aneurysm of the inferior mesenteric artery (IMA) is reported. This case underlines the importance of a correct diagnosis by instrumental methods such as Duplex Scanner, CT and Arteriography, mainly when the first diagnosis is aneurysm of the abdominal aorta (AAA). Our patient showed, furthermore, the occlusion of the celic axis, of the superior mesenteric artery and of both hypogastric arteries; thus his intestinal vascularization was represented, from the gastric fundus until the rectum, only by the inferior mesenteric artery and its collateral network. The operation consisted in the resection and reimplantation of the vessel on the left side of the terminal abdominal aorta, after removal of the dilated segment. This location was chosen because of the coexistence of a mild dilatation of the aorta of 2.8 cm and considering possible aortic surgery for AAA in the future.

Abstract
A case of post stenotic aneurysm of the inferior mesenteric artery (IMA) is reported. This case underlines the importance of a correct diagnosis by instrumental methods such as Duplex Scanner, CT and Arteriography, mainly when the first diagnosis is aneurysm of the abdominal aorta (AAA). Our patient showed, furthermore, the occlusion of the celic axis, of the superior mesenteric artery and of both hypogastric arteries; thus his intestinal vascularization was represented, from the gastric fundus until the rectum, only by the inferior mesenteric artery and its collateral network. The operation consisted in the resection and reimplantation of the vessel on the left side of the terminal abdominal aorta, after removal of the dilated segment. This location was chosen because of the coexistence of a mild dilatation of the aorta of 2.8 cm and considering possible aortic surgery for AAA in the future.
