Abstract Background PVT is an ultrasonographic finding in up to 8% of patients with liver cirrhosis. Once hepatocellular carcinoma has occurred as the final station in liver cirrhosis, the risk of PVT rises to 40%. Benign and malignant PVT can occur in patients with liver cirrhosis, and it is important to differentiate the nature of PVT as it has a great impact on patient’s management and outcome. Diagnosis Confirming portal vein thrombosis and extension by abdominal ultrasound, contrast-enhanced USG, CT, or MRI. Malignant criteria of PVT are pulsatile pattern in Doppler and heterogeneous contrast enhancement, which are especially seen at the arterial phase, neovascularity within PVT, portal vein thrombus with a diameter of > 23 mm while in benign thrombus, PV diameter does not exceed 20 mm. Visible hypervascular tumor is in close proximity to PVT. Conclusion It is not uncommon to find portal vein thrombosis in patients with liver cirrhosis, despite the fact that malignant variant is the most frequent, but efforts should be gathered to exclude benign PVT which may change the management of the patients dramatically.

Portal vein thrombosis (PVT) is a frequent complication of liver cirrhosis and its prevalence increases with the severity of liver disease. Patients with liver cirrhosis and hepatocellular carcinoma may have either malignant or blunt (benign) PVT. In these patients, the diagnosis and characterization of PVT is important for the prognosis and further treatment.Ultrasound (US) is the modality of choice for the diagnosis of PVT. The features of PVT on B-mode (gray-scale) US include: dilatation of the portal vein, visualization of the thrombus and, in chronic PVT- cavernous transformation. Sensitivity of US in the diagnosis of PVT is improved by the use of Doppler US and of ultrasound contrast agents. In the latter years, contrast enhanced ultrasound (CEUS) showed high sensitivity in the differential diagnosis between benign and malignant PVT and could be the diagnostic method of choice for the characterization of PVT. Blunt thrombi are avascular and will not enhance during CEUS examination, while a hyperenhancement pattern of the portal thrombus in the arterial phase, with “wash out” in the portal or late phase is typical for malignant PVT.
