title: CT features of non-malignant portal vein thrombosis: a pictorial review.
abstract: Portal vein thrombosis (PVT) is a rare clinical entity in general population, but a relatively frequent entity in liver cirrhosis. Severe PVT-related complications are potentially lethal, such as ischemic intestinal infarction and complications of portal hypertension. Additionally, occlusive PVT can not only increase the incidence of variceal rebleeding, but also significantly decrease the cirrhotic patients' survival. Based on the clinical significance of PVT, early diagnosis is very critical to allow for rapid establishment of appropriate treatment and improvement of prognosis. Dynamic CT scan is an important diagnostic modality of PVT. The objective of this pictorial review is to illustrate various CT features of non-malignant portal vein thrombosis and its associated abnormalities. Evolution of portal vein thrombosis, such as stage, degree, and extension of thrombus, can be evaluated according to CT demonstrations, which is helpful to timely adopt appropriate treatment modality. Other associated CT findings include the dilation of collateral veins around the obstructed portion of portal vein and the hepatic perfusion and morphology abnormalities.
