Axial section of triphasic abdominal CT scan at the level of upper liver shows heterogeneous liver parenchyma on precontrast image (A) that shows caudate lobe and central parenchymal enhancement on arterial and portal phases (B and C). The periphery of the liver enhances with central low density on delayed image (D). The middle and left hepatic veins are not visualized, while right hepatic vein and intrahepatic IVC have luminal narrowing (blue and white arrows on C respectively).

On the abdominal CT scan, the left and middle hepatic veins were not visualized; the right hepatic vein and intrahepatic IVC had luminal narrowing, and there was caudate lobe enlargement (Figures 1 and 2).
Axial (A and B) and coronal (C) portal venous phase abdominal CT scan at different levels show caudate lobe enlargement (double arrow on A), splenomegaly (star on C) and esophageal varices (arrow on B). The portal veins are patent (arrowheads on A and C).
