Subarachnoid Hemorrhage in Subacute Bacterial Endocarditis

Abstract

A clinical pathologic study of 4 cases in which subarachnoid bleeding was due to a ruptured cerebral aneurysm. In 2 cases the aneurysm was of mycotic origin and in 2, of the "congenital" or berry type with secondary arteritis of the wall. In view of the frequency of "congenital" aneurysms of the circle of Willis the opinion is expressed that mere coexistance of subacute bacterial endocarditis and cerebral aneurysm is insufficient to establish the mycotic origin of the aneurysm.
