摘要：

Metastasis of a cardiac myxoma to the brain is extremely rare. We present the case of a 70-year-old man who had an atrial myxoma and two metastatic myxomas in the brain. The intra-cranial lesions were in fact diagnosed before the cardiac myxoma, since the patient developed hemiparesis before his cardiac symptoms occurred. Computerized tomography of the brain showed two high-density lesions, the larger of which was removed surgically. Follow-up computerized tomography revealed a progressive enlargement of the second lesion which was then resected. Histopathological examination showed all lesions to the benign myxomas. Interestingly, high concentrations of interleukin-6 were present in the patient’s serum and cardiac myxoma. Interleukin-6 may possibly potentiate metastasis of cardiac myxoma.
