Portal venous system thrombosis
The portal venous system consists of the mesenteric, splenic, and portal veins. Occlusion of portal veins causes congestion of liver, spleen and bowel loops due to increased venous pressure and the development of venous collaterals. Acute thrombosis may be difficult to detect in non-contrast basis as the thrombus may be iso or hypodense and not usually be hypedense. The diagnosis is made on portal venous phase contrast enhanced studies.
