Abstract

Portal vein aneurysms are focal dilatation of the portal venous system and have attracted clinical attention in recent years. The most common sites of portal vein aneurysms are the main portal vein and the confluence of the splenic and the superior mesenteric veins. The associated liver cirrhosis and portal hypertension have been thought to be main causes of portal vein aneurysms. We reported on an 86-year-old man with portal vein aneurysm. The imaging findings were presented and the relevant literature was also briefly reviewed.
