目的：探讨出血型烟雾病的CT影像学特点。方法回顾性分析25例出血型烟雾病患者的CT影像学资料，分析出血部位与侧支血管形成及灌注特点的关系。结果3例在左侧丘脑区及额叶出现局限性高灌注表现，22例未发现灌注异常；10例（40％）出血部位为丘脑，8例（32％）出血部位为脑室内，7例（28％）出血部位为蛛网膜下腔；25例（100％）均出现不同程度的侧支血管代偿情况。结论出血型烟雾病脑灌注特点大多数表现为正常或局限性高灌注，这与出血部位及侧支血管形成情况有密切关联。

Objective To analyze CT manifestations of cerebral perfusion imaging of hemorrhagic moyamoya disease .Meth-ods A retrospective analysis was made of the CT cerebral perfusion imaging data of 25 patients with hemorrhagic moyamoya disease , and the correlation between the bleeding site , the formation of collateral vessels and perfusion characteristics was explored .Results Three of the patients showed localized hyperperfusion in the left thalamic and frontal lobes , and 22 showed normal perfusion .Ten cases (40%) developed bleeding in the thalamus , eight cases (32%) in the ventricle and seven cases (28%) in subarachnoid.There was compensation of collateral vessels to different degrees in all the patients ( 100%) .Conclusions Hemorrhagic moyamoya disease is characterized by normal perfusion or localized hyperperfusion , which is closely associated with the bleeding site and collateral vessel formation.
