[Aneurysm of the portal vein: report of two cases].
Portal venous aneurysms are very rare entities, which are described as focal dilatations of the portal venous system. There are two types: intrahepatic and extrahepatic. Portal hypertension is the most important etiologic factor in the development of portal vein aneurysm. In this case report, ultrasonography, color Doppler ultrasonography and magnetic resonance angiography findings of two cases with portal vein aneurysms and portal hypertension are presented and correlated with the literature. Consequently, color Doppler ultrasonography in the demonstration of portal vein aneurysm is highlighted.
