Abstract

Approximately 4% of cerebral aneurysms are of mycotic origin. The destination of "mycotic" for arterial lesions of infectious origin was provided by Osler in 1885, and the relationship of mycotic aneurysms in any location to bacterial endocarditis was made clear by the review of Stengel and Wolferth in 1923. Mycotic aneurysms are abnormalities of the vessel wall resulting from infacted emboli, most commonly arising from the heart as a part of the spectrum of bacterial endocarditis. The middle cerebral artery is most commonly involved, including its proximal division which is a common site for congenital aneurysms also. Recently we experienced a case of middle cerebral mycotic aneurysm ruptured into the lateral ventricle and successful removal of the hematoma after clipping of the aneurysm. The patient was discharged unevently in mild left hemiplegias we discussed with a brief review of the literature.
