22 cases of Moyamoya disease were analyed clinically and an interesting case with aneurysm coincided with the hemorrhagic point was presented. 7 of 22 cases were children and 15 were adult. Female was about 3 times as much as male, i. e., 5 males and 17 females. Initial symptoms were ischemic attack in 7 of 22 cases, convulsive seizure in 5 cases and intracranial hemorrhage in 10 cases.<BR>All cases which had intracranial hemorrhage as initial symptom were females over 17 years old. Rebleeding occurred in 2 cases, one of which associated with a small aneurysm localized in periphery of Heubner's artery. Its aneurysm ruptured during lt-cerebral angiography, which showed the extravasation into the ventricular system.<BR>By repeating the lt-CAG, the spontaneous regression and final disappearance of this aneurysm were demonstrated. It was supposed that the aneurysm as discribed above was a false one, which suggested initial hemorrhagic point.
