Evaluate liver mass. Provided history of hepatocellular carcinoma. ABDOMEN:LIVER, BILIARY TRACT: The liver morphology and contour is unremarkable. In the right hepatic lobe segment 7/8 there is a large mass measuring 12.0 x 9.1 cm x 11.8 (series 9/40) which is heterogeneously mildly T2 hyperintense with a centrally T2-weighted hyperintense stellate scar-like component. The mass is lobular in contour with avid late arterial homogeneous enhancement without significant enhancement of the central scar-like component, which may represent central necrosis. On portal venous and three-minute delayed imaging there is washout of the lesion with persistent enhancement of numerous internal septations resulting in a mosaic type appearance.Along the superior anterior aspect of the mass there appears to be a discrete 1.9 x 1.7 cm satellite nodule (series 10/36). Additionally, in the periphery of segment V (series 10/77) there is an arterial-enhancing focus measuring 1.0 cm without contrast retention or definite wash-out, non-specific.The anterior branch of the right portal vein is not well opacified and may be thrombosed without specific evidence of tumor thrombus. The hepatic veins are patent. The right hepatic vein is distorted by the mass. The hepatic artery appears patent.No biliary ductal dictation.Normally distended gallbladder.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. 12 cm right hepatic lobe mass with signal characteristics compatible with stated history of hepatocellular carcinoma, adjacent satellite nodule seen. Additional non-specific segment V 1.0 cm lesion. 2. Probable thrombosis of the anterior division of the right portal vein.
