RESUMO
A 72âyearâold man with hepatocellular carcinoma(HCC)was treated with transarterial chemoembolization(TACE)and radiofrequency ablation(RFA). Six months after RFA, gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gdâ EOBâDTPA)âenhanced magnetic resonance imaging(MRI)revealed multiple metastatic recurrences in the liver. TACE was performed for the recurrent HCC. However, the treatment response on the GdâEOBâDTPAâenhanced MRI showed that the lesions had advanced and that the liver metastatic nodules had ringâshaped contrast effects. We suspected metastatic liver cancer based on the MRI findings and performed colonoscopy. Finally, we diagnosed the patient with multiple hepatic metastases of sigmoid colon cancer based on the results of the endoscopic colon biopsy and percutaneous liver tumor biopsy. In conclusion, we had a teachable case of the treatment of HCC.
