摘　　要：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.
