Multiple cerebral aneurysms originating from previously resected cardiac myxoma

Primary cardiac tumors are very rare, accounting for 0,001 ­0,03% in autopsy series, cardiac myxoma (CM) account for approximately 50% of them. Association between CM and cerebral aneurysm is well documented in this condition but the occurrence of cerebral aneurysm after resection of CM is very rare, with only 40 reports in medical literature. We present a case of a 45 years old female patient with multiple cerebral aneurysms 2 years after a successful resection of cardiac myxoma, submitted to radiosurgery for 2 bigger aneurysms with good results. This report ads to literature new clinical findings and a hypothesis of radiosurgery as an effective option of treatment for cerebral aneurysms with origin in CM.
