Enhanced CT scan before hepatectomy. A: Arterial phase image showing a large, heterogeneous mass of the liver with hypodense areas, which had clear border between tumor and the normal liver. Lesion showed heterogeneous enhancement and the high density of tumor blood vessels was seen in this region, lower density area to the central region as the center radial arrangement. Left hepatic vein was be compressed by the tumour and turned out to be rigidity. B: Venous late phase images showing a large, solid mass of the liver. Large hypodense tumor of the right hepatic lobe with an enhancement of the peripheral portion. The tumour was diffuse enhanced with a lager hypodense area in the center thought to be necrosis.
