64-year-old female with history of HCC, status post TACE/RFA. Assess for recurrence of HCC. ABDOMEN:LIVER, BILIARY TRACT: Cirrhotic morphology. Stable small ablation cavity in hepatic segment 5 (series 10 image 142) without evidence of arterial hyperenhancement or washout. Capsular rim enhancement on the delayed phase (series 11 image 37) is unchanged and likely represents fibrous tissue.A subcentimeter focus of arterial enhancement in the peripheral hepatic segment 6 (series 10 image 26) is isointense on the remaining series and favored to represent a perfusional variant.Abutting a punctate cyst in hepatic segment 6 (series 7 image 21) is a sub 5 mm T2 hyperintense enhancing focus that persists on the delayed phase (series 11 image 45). The cyst is unchanged since the 2014 MRI exam, however this small area of enhancement abutting the cyst is new.No intra or extrahepatic biliary ductal dilatation. Status post cholecystectomy.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Small left renal cyst. No hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Bilateral breast prostheses noted.OTHER: No significant abnormality noted.
1.Stable small hepatic segment 5 ablation cavity without evidence for local recurrence or new enhancing lesion with washout.2.Abutting a punctate cyst in hepatic segment 6 is a sub 5mm T2 hyperintense enhancing focus that persists on the delayed phase. The cyst is unchanged since the 2014 MRI exam, however the small area of adjacent enhancement is new. This may represent a vascular flow effect but unlikely to represent hemangioma as not seen on prior. Attention on follow-up imaging is recommended.
