BACKGROUND: Radiofrequency ablation (RFA) is a thermal ablation technique which results in coagulative necrosis. Several preliminary studies have evaluated the efficacy of RFA for liver tumor and benign prostate disease, but few studies for lung tumor. We experienced RFA for a metastatic lung tumor and it was effective. CASE: A 61-year-old woman was admitted to our hospital with chest pain. Extended thymothymomectomy with lymph node dissection was performed after diagnosis of thymic carcinoid. After 14 months, multiple small lung nodules, which had been 5-10 mm in diameter, were appeared and resected. However, 23 months after the first operation and 14 months after the second operation, multiple small lung nodules were appeared again and RFA was performed for 1 tumor without any complications. We used RITA 500 PA (RITA Medical Systems, INC.) and quadruple-hook radiofrequency probe with electrodes. Under local anaesthesia and ultrasound guidance, the probe was inserted into the target tumor and the hooks were deployed. The tumor became smaller (35 mm to 25 mm in diameter) in 2 months. CONCLUSION: RFA is an effective and minimally invasive technique to destruct local tumors.
