History of HCC status post intra-operative ablation. ABDOMEN:LIVER, BILIARY TRACT: The left hepatic dome ablation cavity measures 5.4 x 4.3 cm. There is intrinsic intermediate and high T1-weighted signal intensity internally suggestive of proteinaceous/blood products. Within the ablation cavity there is a curvilinear region of intrinsic T1-hyperintensity which does not completely null on subtraction imaging, likely due to mis-registration. No evidence of internal enhancement or marginal recurrent and/or residual disease.In the right hepatic dome there is a 7-mm T2-weighted hypointense, T1-weighted hyperintense subcentimeter focus (series 501/35), without associated arterial enhancement. No suspicious arterial enhancing lesion.Numerous punctate siderotic nodules.Cholelithiasis without cholecystitis. No intrahepatic or extrahepatic biliary ductal dilatation. The vessels are patent.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. Interval RFA ablation of the left hepatic dome lesion without evidence of residual or recurrent disease.2. 7-mm right hepatic dome lesion may represent a dysplastic nodule; attention to this lesion on follow-up surveillance imaging is recommended.
