History of hepatocellular carcinoma status post TACE/RFA. ABDOMEN:LIVER, BILIARY TRACT: Cirrhotic nodular liver morphology.Segment VI ablation cavity measures approximately 4.9 x 4.2 cm (series 9/255). Along the posteromedial aspect of the resection margin there is a vague asymmetric nodular region of late arterial phase enhancement (series 9/64), measuring 1.4 x 1.1 cm. The enhancement appears more peripheral on the more delayed phase imaging with questionable wash-out.Multiple additional punctate arterial enhancing foci without definitive washout.The vessels are patent. Cholelithiasis without cholecystitis.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.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.
Segment 6 ablation cavity with a subtle peripheral posteromedial nodular region of enhancement with questionable washout raises suspicion for residual tumor. The focus is in a similar location to the pre-ablation lesion but is somewhat smaller in size.
