A Case of Familial Moyamoya Disease: A Case in Brother and Sister / 대한소아신경학회지

ABSTRACT

Moyamoya disease is a progressive and occlusive disorder of the cerebral vasculature with particular involvements of the circle of Willis and the arteries that feed it. It occurs commonly in Japan and Korea, but less frequently in the Western countries. The etiology of moyamoya disease is still unclear, but frequent familial occurrence suggests that some genetic factors may be important in its etiology. Approximately 7-10% of moyamoya disease are familial. We experienced 2 siblings with moyamoya disease, and report the case with a review of previously published cases of moyamoya disease within a family.
