10 cases having abnormal angiographical findings which showed the stenosis or occlusion of middle cerebral artery with moyamoya phenomenon were reported.
The characteristics of these cases were summarized as follows.
1) It showed high incidence in female (3 males and 7 females).
2) These patients involved two young cases ranged in age from 4 years to 62 years.
3) Intracranial hemorrhage was cofirmed in 4 cases and onset of symptom in other 6 cases was similar to that of cerebral infarction.
4) 5 cases showed a unilateral occlusion of middle cerebral artery at its origin and 2 cases showed a unilateral stenosis of M1 portion, with moyamoya vessels in this region.
5) Two cases demonstrated bilateral occlusion of middle cerebral artery, and one showed a right stenosis and left occlusion of middle cerebral artery, with moyamoya vessels.
6) On the other hand, we could not find a stenosis on the intracranial internal carotid artery in these cases.
7) These findings suggested that such cases may be different from the so-called“Moyamoya disease”.
