摘　　要：目的探讨基底动脉尖综合征(TOBS)的临床和影像学特征。方法回顾性分析43例TOBS患者临床资料。结果本组患者临床表现主要有意识障碍(38例,88.4%)、眼球运动障碍(31例,72.1%)、瞳孔异常(28例,65.1%),同时伴眼球震颤、肢体瘫痪、共济失调、构音障碍等。MR I检查示病灶常为双侧(67.4%),梗死部位常见于丘脑(65.1%)、脑干(60.5%)、小脑(55.8%)、枕叶(39.5%)和颞叶内侧面(14.0%)。其中双侧丘脑呈基本对称性分布的"蝶形"梗死占丘脑梗死的46.4%。结论 TOBS的临床表现形式多样,主要为意识障碍、眼球运动障碍和瞳孔异常,伴有丘脑、小脑、颞叶内侧面和枕叶梗死的症状。MRI检查示双侧丘脑内侧对称性分布的"蝶形"梗死灶为TOBS的影像学特征。Objective To explore the clinical and image features of top of the basilar artery syndrome（TOBS）.Methods The clinical data of 43 TOBS patients were analyzed retrospectively.Results The clinical manifestations of the patients in this group were unconsciousness（38 cases,88.4%）,disturbance of eyeballs（31 cases,72.1%）,abnormality of pupils（28 cases,65.1%）,and combined with nystagmus,limb paralysis,ataxia,dysarthria,and so on.MRI showed that the infarctions were mostly double（67.4%）,and the locations of infarction were thalami（65.1%）,brainstem（60.5%）,cerebellum（55.8%）,occipital（39.5%） and medial surface of lobus temporal（14.0%）.And the ＂Butterfly like＂ lesions was 46.4% of the thalami infarction.Conclusions TOBS has various clinical manifestations.The main symptoms are unconsciousness,disturbance of eyeballs and abnormality of pupils,and always combined with the symptoms of thalamus,cerebellum,medial surface of lobus temporal and lobus occipital infarction.The marked imaging features of TOBS is ＂Butterfly like＂ lesions located in double thalami by MRI.
