Delayed Cerebral Metastases from Completely Resected Cardiac Myxoma: Case Report and Review of Literature

Cardiac myxoma is the most common benign tumor of the heart. However, low incidence of recurrence and metastasis has been reported. A 49-year-old female patient was admitted in the hospital due to sudden onset of left side weakness. Magnetic resonance imaging (MRI) of brain showed multifocal areas of diffusion restriction on diffusion weighted images. Echocardiography was performed to evaluate the cause of embolic brain infarction and cardiac myxoma was found in the left atrium. The patient underwent complete excision of the mass. One year later, the patient was readmitted with symptoms of dysarthria. Brain MRI showed newly developed multiple hemorrhagic metastatic lesions. The patient underwent radiotherapy of the metastatic lesions. Although rare, cardiac myxoma can cause delayed metastasis. We report a rare case of delayed multiple cerebral metastases from the completely resected cardiac myxoma.
