[Mycotic intracranial aneurysm in infective endocarditis of the mitral valve].

A 20-year-old woman suffering from mitral valve endocarditis due to streptococcus faecalis infection after blunt trauma and splenectomy complained of severe headache 18 days later. Cerebral angiography showed a left posterior artery aneurysm. A craniotomy was performed and the aneurysm could be successfully removed. The postoperative neurological status showed a mild transient right hemiparesis. The patient underwent mitral valve replacement with a St. Jude-Medical prosthesis 14 days after brain surgery. The patient was in stable neurologic and hemodynamic conditions at the time of discharge 3 weeks after valve replacement.
