title: [Isolated intracavitary metastatic hepatocellular carcinoma of the right atrium without inferior vena cava involvement; report of a case].
abstract: A 63-year-old female had been treated for liver cirrhosis and hepatocellular carcinoma (HCC) since 3 years before. She developed symptoms of dyspnea and echocardiography revealed a large tumor in the right atrium. The stalk of tumor was attached to the intraatrial septum just above the tricuspid valve and the tumor was floating between the right atrium and the right ventricle according to cardiac rhythm. The size of tumor was 30 x 15 mm in diameter. She was admitted to our hospital for emergency operation. She was operated for cardiac tumor under cardiopulmonary bypass successfully and the postoperative course was uneventful. But the pathology reported direct intracavitary metastasis of HCC without intravascular involvement. She was discharged on the 7th postoperative day for the treatment of HCC.
