Male; 75 years old. Reason: obstruction? History: s/p RFA with increasing bili and LFTs ABDOMEN:LIVER, BILIARY TRACT: Interval posttreatment changes from thermal ablation of segment 8 HCC with new wedge-shaped area of non-enhancement spanning segments 8/5 and measuring up to 8.5 x 7.6 cm in greatest axial dimension (series 1101/3495). Increased T2 signal within this area, most likely due to post treatment edema. New mild perihepatic ascites. New mild intrahepatic biliary ductal dilation in the right and left hepatic lobes with poor visualization of the confluence of the right and left main hepatic ducts near Klatskin's point, which may be due to the posttreatment edema which extends to this location (series 301/22). Normal extrahepatic common duct is seen.Portal and hepatic veins are patent. Hepatic artery is patent.Cirrhotic liver morphology. No evidence of residual or recurrent segment 8 HCC. Previously described segment 2 and 3 arterially hyperenhancing lesions on prior CT are not appreciated on postcontrast sequences on the current MRI. No focal lesions which meet the criteria for HCC. Cholelithiasis.SPLEEN: Stable splenomegaly and perigastric varices.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: T2 hyperintense right adrenal lesion, stable in size and again likely the sequela prior of hemorrhage.KIDNEYS, URETERS: Small left inferior pole renal cyst.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. Posttreatment changes from recent thermal ablation of segment 8 HCC, as detailed above. No evidence of residual or recurrent disease.2. New intrahepatic biliary ductal dilation, which may be due to posttreatment change/edema extending to Klatskin's point. Continued follow up is suggested.
