History of hepatocellular carcinoma status post TACE/RFA. Examination somewhat limited by technical factors including suboptimal postcontrast images.ABDOMEN:LIVER, BILIARY TRACT: Cirrhotic liver morphology. In hepatic segment 4A, there is a T1 hypointense structure with peripheral intrinsic T1 shortening overall measuring 3.3 x 3.2 cm (series 10, image 271) corresponding to the HCC ablation cavity. Along the posterior superior aspect of the ablation cavity, there is a small area of increased arterial enhancement (series 10, image 276) without washout on more delayed images which is nonspecific but may reflect posttreatment change or perfusional variation. No additional focal enhancing lesions are identified.There is a large (3.6 cm) gallstone. No pericholecystic inflammatory changes to suggest cholecystitis. No biliary ductal dilatation.Multiple perihepatic portosystemic collaterals.SPLEEN: No significant abnormality noted.PANCREAS: There is a 5 x 7 mm T2 hyperintense structure in the pancreatic body along the distribution of the pancreatic duct which is favored to reflect a sidebranch IPMN. 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.Examination mildly limited by technical factors including suboptimal postcontrast images.2.Posttreatment changes related to HCC ablation. Area of enhancement along the posterior superior aspect of the ablation cavity does not washout on more delayed images of this favored to reflect posttreatment change or perfusional variation rather than recurrence/residual tumor. However, continued attention to this area on follow-up examinations is recommended.3.Subcentimeter cystic lesion within the pancreas favored to reflect a sidebranch IPMN.
