Female 58 years old Reason: assess liver lesion History: HCC ABDOMEN:LIVER, BILIARY TRACT: Nodular hepatic contour with widening of the fissures consistent with hepatic cirrhosis.Reference ablation defect in the right hepatic lobe measures 1.6 x 1.1 cm, unchanged (series 13/31). There is increased peripheral arterial enhancement but without washout. Again the lesion demonstrates mild intrinsic T1 hyperintensity and subtle T2 hyperintensity.Reference subcapsular ablation defect in the right hepatic lobe has decreased in size and is no longer discretely measurable.There is additional geographic increased arterial enhancement in the right hepatic lobe, most compatible with transient hepatic arterial differences (THAD).Patent hepatic vasculature.SPLEEN: Marked splenomegaly Stable T2 hyperintense lesion within the posterior spleen which may represent a small hemangioma.PANCREAS: 1.0 x 0.7 cm T2 hyperintense lesion within the pancreatic body, compatible with IPMN and not significantly changed compared to prior (series 7/24).ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Stable bilateral renal cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.
1.Posttreatment changes relating to prior TACE/RFA. Though there is increased peripheral arterial enhancement of the largest reference lesion in the right hepatic lobe, this finding is likely related to transient hepatic arterial differences. The findings do not meet the criteria for HCC. However, attention to this area at follow-up is recommended. 2.Stable pancreatic body IPMN.
