摘　　要：目的探讨CT、DSA对成人出血性烟雾病(Moyamoya)的诊断价值,以提高诊断水平。方法回顾性分析10例成人型出血性烟雾病的CT与DSA的表现,CT均为平扫,DSA均为经股动脉插管行全脑动脉血管造影。结果10例患者CT检查患者颅内有不同部位出血灶,大多表现为多部位出血,以脑实质和脑室出血为主。DSA显示所有病例均有不同程度异常血管网形成;其累及血管为双侧或单例颈内动脉系统、伴颈外系统的病变(颞浅动脉、脑膜中动脉)、基底动脉和/或大脑后动脉和/或椎动脉。结论在排除其他原因所致的脑出血后,CT可初步提示本病的诊断,明确诊断有赖于DSA。Objective To evaluate CT and DSA in the diagnosis of hemorrhagic Moyamoya disease in adults. Methods Both CT and DSA findings in 10 adult with cerebral hemorrhage, who were confirmed with Moyamoya disease were retrospectively studied. CT non-contrast enhanced scan and DSA were performed in all patients. Results Multiple sites of hemorrhage located in brain as well as the ventricles were found on CT scan. On DSA, the stenosis of internal carotid arteries and the middle cerebral arteries were observed, and collateral vessels were revealed in cerebral hemispheres. Conclusion CT finding can suggest the diagnosis of the disease, and the final diagnosis should be confrimed by DSA.
