Celiomesenteric trunk with concurrent aneurysm: report of a case.

This report describes a rare case of a common celiomesenteric anomaly with a concurrent aneurysm demonstrated by contrast-enhanced multidetector computed tomography (MDCT) angiography. The patient, a 53-year-old man, had no abdominal pain or discomfort. Abdominal CT scanning was performed because of hypoglycemia. Celiac digital subtraction angiography (DSA) was carried out 10 days after CT angiography. The CT angiographic images clearly showed a saccular aneurysm originating from the bifurcation of a common celiomesenteric trunk. The origin and course of the hepatic, splenic, and superior mesenteric arteries were also visualized. These findings were confirmed by intraarterial DSA. The lesion was resected surgically because of the risk of a rupture of the aneurysm, and the superior mesenteric artery was replanted into the celiomesenteric trunk.
