In this study, a case of peritoneal and pleural dissemination after radiofrequency ablation was reported. A man in his 60's with hepatitis B virus infection was diagnosed with hepatocellular carcinoma (HCC) measuring approximately 18 mm in diameter in the posterior segment, which was observed in computed tomography (CT) images. HCC was treated by radiofrequency ablation using a cooled-tip needle and with CT-guided transpulmonary approach combined with transarterial chemoembolization. Technical success was achieved immediately after the procedures, and no complication was identified. CT images obtained 8 and 10 months after radiofrequency ablation showed a subphrenic nodular lesion and pleural mass, both of which gradually enlarged during the follow-up periods, although local reoccurrence was not recognized. Fourteen months after the radiofrequency ablation, peritoneal dissemination was confirmed at laparotomy and by histological diagnosis.
