Abstract: | Only scattered reports of portal vein and superior mesenteric vein aneurysms appear in the literature. Case reports of three
patients with portal vein and superior mesenteric vein aneurysms diagnosed by computed tomography (CT) and gray-scale, color
Doppler, and duplex Doppler sonography are presented. In one case, an isolated portal vein aneurysm was demonstrated. In the
second case, an aneurysm of the portal vein and superior mesenteric vein resulting in biliary ductal dilatation was observed.
In the third case, an isolated superior mesenteric vein aneurysm was found. None of the patients had a history or clinical
evidence of underlying liver disease, pancreatitis, or other disease states that would predispose them to the development
of aneurysms. The clinical presentations, possible etiologies, and imaging features of portal vein and superior mesenteric
vein aneurysms are reviewed. The value of CT and sonography in the detection and characterization of these rare aneurysms
is discussed.
