Focal narrowing or waisting of the intrahepatic inferior vena cava with a linear filling defect.
Hepatomegaly, including the caudate lobe, and heterogeneous enhancement of the liver parenchyma. Segment V is notably hypodense to the rest of the liver. Also, multiple small nodules are seen throughout the liver.
The hepatic veins are not visualized. The portal vein is normal in caliber and enhances homogeneously. There are few collateral vessels (e.g. hepatorenal, recanalized umbilical vein).
