  		Figure 3. Oblique coronal three-dimensional CT cholangiogram obtained in the same patient as in Figure 2 shows a trifurcation at the upper confluence (arrow) and a small branch (arrowhead) from segment 4 that drains into the middle right hepatic duct.

  		Figure 4. Oblique coronal three-dimensional CT arteriogram in the same patient as in Figure 2 shows a doubled left hepatic artery (thin arrows) coming from the common or proper hepatic arteries. The biliary system is still contrast enhanced and shows the trifurcation at the upper confluence (thick arrow) and the topographic relationship of both branches of the systems. A doubled renal artery (arrowhead) is depicted posterior to the splenic vein.

  		Figure 5. Oblique coronal three-dimensional CT angiogram in the portal or hepatic venous phases in the same patient as in Figure 2. The right and middle hepatic veins fuse (arrow) proximal to the inferior vena cava. The biliary system is still contrast enhanced and shows the topographic relationship of both systems.
