Contrast-enhanced CT images. Axial projection (a); sagittal-oblique projection (b). The arrows in (a) and (b) show a shunt between the posterior wall of the portal vein (PV), just before its intrahepatic hilar division, and the inferior cava vein (ICV); the intrahepatic portal branches appear reduced and filiform (arrowhead in (a)).

Axial contrast-enhanced CT images. The arrow shows the shunt between the portal vein (PV) and the inferior cava vein (ICV); at the hepatic hilum, the PV appears enlarged with only one intrahepatic portal branch (arrowhead).

The portocaval shunt had only one intrahepatic portal branch, which was of lower caliber (Figure 2).
