[Case with cardiac myxoma causing cerebral metastasis after cardiac tumor resection].

ABSTRACT

We report a case of cardiac myxoma causing cerebral metastasis after cardiac tumor resection. A 68-year-old man with a cerebral infarction was admitted to our hospital. A cardioembolic source was suspected and echocardiography was performed. In that examination, a cardiac tumor was found in the left atrium. Tumor resection was performed urgently and his postoperative course was uneventful. After the operation he had no new episodes of cerebral deficit. However 6 months after the operation, he complained of headaches. The brain computed tomography (CT) showed there were multiple high-density areas. One of the tumors was resected and the tumor was diagnosed pathologically as metastasis of cardiac myxoma. Brain metastases were treated with 40.8 Gy whole-brain radiation therapy. As the result the tumors were effectively treated and reduced.
