Seven cases with intracranial hemorrhage associated with adult moyamoya disease were observed by computed tomography in acute stage. Intracranial hemorrhages in this condition are divided into two types according to main site of hemorrhage, a) intracerebral hematoma and b) intraventricular hemorrhage. None has obvious clots in subarachnoid spaces or basal cisterns. Intracerebral hematoma in this condition is indistinguishable from that in other etiologies. However, intraventricular hemorrhage without clot in parenchyma nor in basal cistern is thought to be specific to moyamoya disease. From the observation of cases reported here we believe that the hemorrhage occurs initially in cerebral parenchyma or near or within lateral ventricle in this disease.
