Celiomesenteric Trunk Aneurysm: A Case Report

Abstract: A celiomesenteric trunk (CMT) is an extremely rare anatomic variant that consists of celiac and superior mesenteric arteries having a common origin from the aorta. CMT accounts for less than 1% of all splanchnic artery anomalies. Aneurysm involving a CMT is an even rarer vascular abnormality, and, to our knowledge, only eight cases of CMT aneurysm have been reported in literature. We describe a case of the incidental finding of CMT aneurysm in an asymptomatic patient. It was found after dorsolumbar column radiography and successive computed tomography and arteriography confirmed the diagnosis. Even if asymptomatic, we decided to repair it surgically with aneurysmectomy and suture of the neck due to risk of rupture
