Mycotic aneurysm is a redoubtable complication of infectious endocarditis which is the source of many other complications and is generally difficult to diagnose. They are secondary to the migration vegetations in the cerebral circulation, which, depending on its septic nature or not, can give different clinical pictures: ischemic embolic vascular accidents, meningitis, cerebral hemorrhages and brain abscesses. We report in this article a case of a 36-year-old patient, hospitalized in the cardiology department for infective endocarditis, who suddenly presented with intense headaches without any other associated signs. A cerebral scan (Fig-1) was carried out in emergency, which was in favor of a subarachnoid hemorrhage with demonstration of a saccular aneurysm of the terminal portion of the basilar trunk. Two days later, for a better characterization, the patient underwent a cerebral arteriography (Fig-2) which revealed an aneurysmal dilation of the terminal portion of the basilar trunk of mycotic origin.
