Percutaneous transhepatic portal vein embolization (PTPE) is performed to reduce the risk of postoperative liver failure after major liver resection. Although some adverse events of PTPE were reported in previous papers, needle-tract implantation has not been reported. We report a case of hepatocellular carcinoma (HCC) with needle tract implantation of the right thoracic wall and diaphragm, which is strongly suspected to have been caused by PTPE.<BR>A man in his at late 50s was admitted to our hospital with a solitary HCC in segment VIII of the liver. Preoperative PTPE through puncturing the right portal vein under sonographic guidance was successfully performed without complications using a mixture of gelatine sponge and lipiodol. Right hepatic lobectomy was performed 22 days later. 13 months after PTPE, contrast-enhanced CT and MR image showed needle-tract implantations in the intercostal muscles and diaphragm at the puncture site of PTPE. He underwent resection of the right thoracic wall tumor and diaphragm. Pathological examination confirmed metastatic HCC.
