A case of unilateral moyamoya disease suffered from intracerebral hemorrhage due to the rupture of cerebral aneurysm which appeared seven years later

摘要

Background:Whether unilateral moyamoya disease (MMD), confirmed by steno-occlusive lesion at the terminal portion of internal carotid artery with formation of moyamoya vessels unilaterally and normal or equivocal findings contralaterally, is an early form of definite (bilateral) MMD remains controversial. It is well-known that adult patients with MMD tend to suffer from cerebral hemorrhage, occasionally due to the rupture of aneurysm arising from moyamoya vessel.
