    A 50-year-old woman with a liver mass on abdominal ultrasonography was referred for further evaluation. HBs antigen and HCV antibody were negative, but HBs antibody and HBc antibody were positive. Liver function tests were normal. A 24×15 mm low echoic mass was seen in segment 4 of the liver on ultrasonography. Enhanced sonography showed early enhancement with drainage via the hepatic vein. In the Kupffer phase, the tumor appeared as a defect. Abdominal enhanced CT and MRI demonstrated a high-density mass in the arterial phase and wash out in the portal phase. Based on these imaging findings and the possibility of occult HBV, we suspected hepatocellular carcinoma and a segment 4 resection was performed. Histopathologically, perivascular epithelioid cells and a few fat cells were seen. Immunohistochemically, HMB-45, MelanA and αSMA were positive. The tumor was diagnosed as a hepatic angiomyolipoma, which may be difficult to distinguish from hepatocellular carcinoma.

    Here, we report a case of radiofrequency ablation therapy (RFA) for liver metastases from colon cancer in a patient with deep-brain stimulation for Parkinson's disease.
    A 73 -year-old man was admitted to our hospital for the metastases in the liver from rectal cancer. He was inserted into the anterior chest; (DBS Deep Brain Stimulators) deep brain stimulation device for Parkinson's disease in 2006. He underwent low anterior resection for rectal cancer in our hospital. Eighteen months later, he was pointed out metastatic lesions at segment 4-8 in liver by abdominal computed tomography.
    We performed RFA under stopping deep-brain stimulation. During RFA, he had are no tremor of Parkinson disease. Electromagnetic interference was not observed during and after RFA. With careful management, RFA is potentially useful treatment strategy for patients with deep-brain stimulation for Parkinson's disease.

    We experienced a patient, 60s old male, who developed hepatocellular carcinoma (HCC) 5 years and 17 years after sustained virological response (SVR) of interferon (IFN) therapy for chronic hepatitis C. In 1993, he received IFN therapy and achieved SVR. Before the therapy, his liver histology showed F1A1. In 1998, 5 years after SVR, he was found to have a HCC, 5 cm in diameter, in the segment 3 and received hepatic resection. The HCC was well-to-moderately differentiated, and histology of the back ground liver was F2A1. In 2010, 17 years after SVR, another HCC, 3 cm in diameter, was detected in the segment 7. We treated the lesion by combination of transcatheter chemoembolization and radiofrequency ablation. Once HCC occurs after SVR, the possibility of developing another HCC will increase in spite of receiving radical treatment. Our case indicates the need for long-term surveillance for HCC recurrence after SVR.

    The case pertains to a 58-year-old man. Following hemostasis for a ruptured hepatocellular carcinoma (HCC) by transcatheter arterial embolization, a right hepatectomy was carried out in April, 2006. Subsequently, increased AFP and PIVKA-II as well as an intrahepatic neoplastic lesion and intrasplenic neoplastic lesion were observed, resulting in the patient being admitted to our hospital for the purpose of closer inspection and medical treatment. He was preoperatively diagnosed to have recurring HCC and liver spleen metastasis, and therefore partial hepatectomy as well as splenectomy were conducted in February, 2010. The patient was diagnosed with recurring HCC and liver spleen metastasis upon histopathological investigation. Lung metastasis, left adrenal gland metastasis, and liver metastasis to the remaining liver were generated following surgery. Partial pneumonectomy was conducted for his lung metastasis, resection of the left adrenal gland was conducted for his left adrenal gland metastasis, and hepatectomy as well as transcatheter arterial embolization were conducted for liver metastasis of his remaining liver; currently, approximately 3 years following the surgeries for spleen metastasis, the patient visits the hospital as an outpatient. Regarding spleen metastasis of HCC, it was believed that a longer term prognosis may thus be achieved by investigating whether or not there are lesions in other organs and then carrying out splenectomy if the disease is controllable.
