Familial Occurrence of Moyamoya Disease: Case Report

There is extensive evidence that moyamoya disease has a tendency for multifactorial inheritance, although the pathogenesis of moyamoya disease is not clear. The authors report a case of familial moyamoya disease involving a 51-year-old female and her 24-year-old daughter, both of whom initially presented, within a 1-year period, withintracerebral hemorrhage and intraventricular hemorrhage. Cerebral angiography showed typical features of moyamoya disease in both patients, but the cause of the pathology remains obscure. The pertinent literature is reviewed.
