The authors report an anomalous fenestration at the M1 portion of the middle cerebral
artery found incidentally in a patient affected with a ruptured aneurysm at the ipsilateral
internal carotid artery(ICA) and unruptured small aneurysms at the contralateral P1 and
ICA. The anomaly was confirmed both angiographically and intraoperatively. A review
of the literature indicated several reports of this same anomaly, many of which were
associated with aneurysms involving either the proximal end of the fenestration or other
cerebral arteries. In the interpretation of cerebral angiograms and during intracranial
operations, clinical attention should be paid to this rare anomaly.
