Giant Fusiform Intracranial Aneurysm in Patient with History of Myxoma

Cardiac myxomas are benign cardiac neoplasms that can send a shower of emboli to cerebral arteries and cause cerebrovascular complications including large, fusiform intracranial aneurysms. These aneurysms result from myxomatous cells invading and weakening the vessel wall and can develop years after myxoma resection. In this clinical image, we illustrate a symptomatic, giant fusiform aneurysm that was discovered and treated 5 years after successful surgical resection of atrial myxoma.
