Conclusion
Formation of cerebral aneurysms secondary to atrial myxoma is rare, with approximately 55 reported cases in the literature.2 This case is unusual in having documented normal vascular imaging several years prior to aneurysm development. We postulate that the embolic event could have occurred at the time of open cardiac surgery to remove the myxoma. A similar embolic mechanism is described in the development of multiple intracranial mycotic aneurysms in the setting of subacute bacterial endocarditis.5 Other risk factors for multiple cerebral aneurysms include autosomal dominant polycystic kidney disease, family history and hypertension.6 Despite its rarity, clinicians should consider left atrial myxoma as a potential cause when faced with multiple fusiform cerebral aneurysms.
