Portal vein aneurysm usually occurs at the junction of the superior mesenteric vein and splenic veins or at the hepatic hilus at the bifurcation of the right and left portal veins [1]. Case Report: Color Doppler and contrast-enhanced dynamic computed tomography scan and computed tomography angiography clearly showed a well-circumscribed, 44x34 mm intrahepatic portal vein aneurysm.
