Moyamoya disease is an uncommon cerebrovascular disorder that is characterized by progressive stenotic change in the terminal portion of the bilateral internal carotid arteries and the formation of an abnormal fine vascular network (the moyamoya vessels) at the base of the brain. The appearance of this vascular network on an angiogram looks like a puff of cigarette smoke drifting in the air; thus, in 1969, Suzuki et al named this novel disorder “moyamoya disease” because the word “moyamoya” means “puff of smoke” in Japanese.
