A 59-year-old man with a known central hepatocellular carcinoma (HCC) underwent a trans-arterial-chemo-embolization (TACE) and a post-TACE percutaneous radiofrequency ablation (PRFA). Two months after the PRFA, the patient presented jaundice and an abdominal computed tomography was obtained. An arterial enhancing mass adjacent to the ablated necrotic lesion with a continuously coexisting mass inside the right hepatic duct, suggestive of a HCC recurrence with a direct extension to the biliary tract was found. Finally a biliary tumor obstruction has been developed and a percutaneous transhepatic biliary drainage was performed. This case of biliary obstruction caused by directly invaded recurred HCC after PRFA will be reported because of its rare occurence.
