Arteriovenous malformation associated with multiple aneurysms including anterior communicating artery aneurysm located in the third ventricle: a case report.

Following the significant advances in neuroradiology, it has been now recognized that an intracranial arteriovenous malformation (AVM) lesion and vascular aneurysm(s) might coexist more often than estimated before. A58-yearold female seen due to a subarachnoid hemorrhage (SAH) was subsequently shown to have an AVM lesion fed by the pericallosal frontopolar, M1 segment of the middle cerebral artery along with three cerebral aneurysms. The AVM lesion was totally excised and the coexisting aneurysms were successfully clipped. As a very rare finding, one of the aneurysms originating from the Anterior Communicating Artery was localized in the 3rd ventricle penetrating the lamina terminalis.
