On physical examination, no tenderness or abdominal rigidity was seen. There was splenomegaly; no palpable abdominal mass was felt. Contrast enhanced computed tomography (CECT) showed liver parenchymal disease with portal hypertension (ascites, collateral and splenomegaly). There was aneurysmal dilatation of the left branch of the portal vein at its bifurcation (<a class="elsevierStyleCrossRef" href="#f0005">Figures 1</a> and <a class="elsevierStyleCrossRef" href="#f0010">2</a>). The main portal vein was dilated, right portal vein, hepatic arteries and vein were normal. Thus, the patient was diagnosed to have liver parenchymal disease with portal hypertension and portal vein aneurysm.<elsevierMultimedia ident="f0005"></elsevierMultimedia><elsevierMultimedia ident="f0010"></elsevierMultimedia>Portal vein aneurysms (PVA) are rare entities.

Medical management includes anticoagulation. Surgical management options include aneurysmorrhaphy, portocaval shunt, and mesocaval shunt. Serial imaging may be advised if PVA are stable and no complications are seen instead of going for surgical or medical treatment.Disclosure or InterestSource(s) of funding or financial interest-Nil."
