Figure 1 Contrast enhanced CT at the level of the portal bifurcation before treatment shows metastasis in segment I (arrowhead), opacified right anterior and posterior segmental portal veins (white arrows), and opacified middle and right hepatic veins (open arrows).

Figure 2 Contrast enhanced CT at the level of the portal bifurcation after treatment shows improved hepatic metastasis in segment I (arrowhead), non-visualization of the thrombosed anterior right segmental portal vein (arrow), opacified posterior segmental portal veins, middle and right hepatic veins, and wedge shaped increased enhancement (open arrows) of the anterior sector secondary to portal vein occlusion.
