Adult cases of moyamoya disease are often admitted as stroke. The purpose of this paper is to clarify the clinical features of moyamoya disease admitted as stroke comparing those of other cases without abnormal vascular networks.<BR>In our hospital, during last five years, 1426 strokes were admitted and examined by cerebral angio-graphy and computerized tomography, the letter of which was omitted in some cases. Among the 1426 cases, there were 9 cases of moyamoya disease comprising 3 males and 6 females. Five cases had attacks of cerebral infarction and 4 cases had those of intracerebral hemorrhage. The age of 9 cases ranged from 30 to 59 years old (47.1 years in average), which was younger than ordinary cases in stroke. All cases of moyamoya disease with cerebral infarction had two or more attacks, while only 20% of the ordinary cases of cerebral infarction repeated attacks. The mortality of the 9 cases was 44% which was almost the same as ordinary cases of stroke and higher than that ever reported.<BR>In consequence, the clinical features of adult cases of moyamoya disease admitted as stroke are almost the same as that of ordinary stroke except for the younger onset and repeating of attacks in cases of cerebral infarction.
