Hepatocellular carcinoma (HCC) with isolated right atrial metastasis is extremely rare; most cases are considered inoperable. We herein report the case of a 74-year-old man with HCC with isolated right atrial metastases without hepatic vein invasion; the right atrial lesion was resected because of the risk of heart failure and sudden death. Postoperatively, he underwent transcatheter arterial chemoembolization and radiofrequency ablation for intrahepatic HCC. He recovered completely, with a long-term survival of 36 months. This is the first report of an HCC patient with isolated right atrial metastases without hepatic vein invasion. Tumorectomy for solitary atrial metastasis is effective for HCC patients.
孤立性右心房转移的肝细胞癌（HCC）极为罕见；大多数病例被认为无法手术切除。我们在此报告一例74岁男性，患有孤立性右心房转移的HCC且无肝静脉侵犯；由于存在心力衰竭和猝死风险，对右心房病变进行了切除。术后，他接受了经动脉化疗栓塞和肝内HCC的射频消融治疗。他完全康复，长期生存达36个月。这是首例关于无肝静脉侵犯的孤立性右心房转移HCC患者的报告。对孤立性心房转移进行肿瘤切除术对HCC患者有效。
