74-year-old male with HCC. ABDOMEN:LIVER, BILIARY TRACT: Cluster of T2 hyperintense foci surrounding the left portal vein (coronal series 5 image 15, axial series 8 image 60) are unchanged and suggestive of peribiliary cysts. Nonenhancing posttreatment effect of the right hepatic lobe and left lateral segment (series 12 image 292) ablation cavities are unchanged. Precontrast T1 hyperintense signal of both ablation cavities (series 1100 image 81) could represent residual blood products. Perfusional changes surrounding both cavities are noted only on the arterial phase. No suspicious lesions showing arterial hyperenhancement or washout are identified to suggest residual or recurrent tumor. SPLEEN: No significant abnormality noted.PANCREAS: Normal bright T1 signal intensity of the pancreatic parenchyma. No pancreatic ductal dilatation.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Stable simple cyst of the right lower renal pole. Additional bilateral subcentimeter T2 hyperintensities are too small to characterize, favor cystic.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Small hiatal hernia.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Sternotomy wires are partially visualized.
1.Ablation cavities of the hepatic dome and left lateral hepatic segment. No evidence of residual or recurrent tumor.2.Small T2 hyperintense foci surrounding the left portal vein are suggestive of peribiliary cysts.
