51-year-old male patient post TACE/RFA. Evaluate for new or recurrent HCC. Reevaluate faint enhancement noted adjacent to segment 7/8 cavity on prior MRI. ABDOMEN:LIVER, BILIARY TRACT: The liver is cirrhotic in morphology. There is a segment 5 lesion cavity measuring approximately 3.9 x 3.2 cm (image 52, series 11). There is no evidence of marginal recurrent or residual disease.The 7/8 ablation cavity measures approximately 3.1 x 2.2 cm (image 71, series 11). Again seen is faint nodular enhancement along the anterior superior aspect of the ablation cavity, appearing similar to the 5/26/2016 study and similar in location to a lesion on a pretreatment scan. There is an additional faint focus of enhancement more posteriorly. Neither of these foci show washout on more delayed imaging. No new suspicious arterial enhancing lesion is identified. Mild diffuse interstitial T2 signal abnormality may reflect mild hepatic fibrosis. The patient is status post cholecystectomy. No intrahepatic biliary ductal dilatation.SPLEEN: The spleen measures 14 cm in length without a focal lesion.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.
1.Postablation changes of segment 5 without specific evidence of marginal recurrent or residual disease.2.Redemonstration of faint nodular enhancement (more anteriorly located focus in particular is at site of preexisting neoplastic lesion when compared to pretreatment imaging) along the segment 7/8 ablation cavity, no washout seen on more delayed imaging. Continued follow up is recommended.
