Large liver mass in the anterior right hepatic lobe, involving segments 8, 5, and 4, with central low-attenuation, peripheral irregular rind-like enhancement, and surrounding hepatic parenchymal edema. There is thrombosis of the middle hepatic vein leading into and coursing along the posterior inferior margin of this mass, with a small amount of clot leading into the inferior cavoatrial junction. There is a similar mass in hepatic segment 7, slightly smaller. Some generalized heterogeneous/diminished perfusion in the segment supplied by the thrombosed middle hepatic vein. There is focal fat along the falciform ligament. No other intra-abdominal abnormalities.
