Multiple Aneurysms on the Same Bifurcation Site of the Middle Cerebral Artery

Multiple aneurysms at the same cerebral arterial branching site are rare, and have been mainly described in a few case reports in comparison with other intracranial multiple aneurysms. Most reported locations of the same artery where multiple aneurysms developed were internal carotid artery and anterior communicating artery. We experienced a very rare case of multiple aneurysms arising at the same bifurcation site of the middle cerebral artery. Only one case like this has been reported previously in the literature. We discussed the preoperative diagnosis and surgical management of such condition.
