Three adult cases of cerebrovascular Moyamoya disease associated with aneurysmal shadow at the peripheral portion of the posterior choriodial artery are reported. According to the follow-up study of carotid angiograms, this aneurysmal shadow is considered to be a pseudo-aneurysm, which indicates a bleeding point in the brain tissue. It has generally been thought that the mechanism of the occurrence of the symptom in adult patient with cerebrovascular Moyamoya disease is due to rupture of vessels in the subarachnoid space on the brain surface. But from our experience, it is suggested that there should be another mechanism, beginning with rupture of vessels in the brain tissue.
报告了3例成年脑血管烟雾病患者，其脉络膜后动脉外周部分出现动脉瘤样阴影。根据颈动脉血管造影的随访研究，这种动脉瘤样阴影被认为是假性动脉瘤，提示脑组织内的出血点。一般认为，成年脑血管烟雾病患者出现症状的机制是由于脑表面蛛网膜下腔血管破裂。但根据我们的经验，提示可能存在另一种机制，即始于脑组织内血管破裂。
