66 year-old male history of HCC. ABDOMEN:LUNG BASES: No significant abnormality notedLIVER, BILIARY TRACT: Ill-defined heterogeneous lesion within the peripheral aspect of segment 6 extending to the capsule demonstrates heterogeneous, but rapid arterial enhancement and washout on subsequent delayed imaging as well as some areas of signal dropout on out of phase imaging. Maximal axial dimensions are 5.4 x 4.0 cm (image 497 of series 1002). There is an additional hyperenhancing focus in segment 8 measuring 7 mm which washes out on delayed imaging, also compatible with HCC (image 557 of series 1002). Other subcentimeter hyperenhancing foci scattered about the liver are indeterminant, but likely perfusional in etiology given appearance and lack of corresponding conspicuity on delayed imaging.The portal veins and hepatic arteries appear patent. No intra or extra hepatic biliary ductal dilatation.SPLEEN: Small splenule.PANCREAS: No significant abnormality notedADRENAL GLANDS: No significant abnormality notedKIDNEYS, URETERS: Bilateral renal cysts, some of which are complex and cortical scars.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality notedOTHER: No significant abnormality noted
1. Large segment 6 mass as above containing fat most compatible with HCC. Additional smaller focus of HCC in segment 8.2. Other scattered areas of hyperenhancement are indeterminant, but favored to be perfusional in etiology however close followup is recommended.
