A 59-year-old male who had undergone partial jejunectomy, partial hepatectomy and microwave coagulation therapy (MCT) seven months earlier for jejunal leiomyosarcoma and liver metastasis was admitted with recurrent liver tumors. Abdominal computed tomography revealed five recurrent tumors located in S2, S4, S6 (two lesions ), S8 of liver, the size of them were less than 2 cm in diameter. PMCT was performed twice for metastatic liver tumors under ultrasound guidance and epidural anesthesia. Pain and fever were not recognized after PMCT. The period of hospitalization was three days. Tumors disappeared in low density area on follow-up CT. After eight months many recurrent lesions were detected in another site of liver. Therefore we performed intra-arterial chemotherapy. This method is thought to be useful for inoperable small multiple metastatic liver tumors, although we have not investigated long-term results of PMCT.
