Aneurysm of the splenic artery which arises from the superior mesenteric artery: a case report.

Aneurysm of the splenic artery which arises from the superior mesenteric artery is a very rare condition with less than twenty cases described in the literature. Most of the time, it is asymptomatic and the diagnosis is fortuitous, but the patient can feel epigastric or left upper quadrant discomfort. One can palpate an abdominal mass or hear an abdominal systolic murmur. The most fatal presentation is the life-threatening rupture. We report the case of a 41-year-old woman presenting an aneurysm of the splenic artery originating from the superior mesenteric artery treated surgically by simple aneurismal resection with neither arterial reconstruction nor splenectomy. The different treatment modalities are discussed, taking into account the presence of the vascular malformation.
