摘　　要：目的分析酷似大脑半球病变的脑桥梗死的临床和影像学特点、定位错误的原因。方法回顾性分析2年间收治的住院患者18例。结果起病时16例患者出现肢体力弱和言语含糊,5例患者出现头晕。查体发现16例患者出现病灶对侧肢体瘫痪,17例患者出现病灶对侧中枢性面舌瘫,16例患者有构音障碍,3例患者有非持续性水平眼球震颤。所有患者均行头颅MRI检查,发现在肢体瘫痪对侧的脑桥均可见片状、条状长T1、长T2异常信号。结论早期行头颅MRI检查有助于发现酷似大脑半球病变的脑桥病变,对于起病时有构音障碍及头晕、临床表现为同侧中枢性面舌瘫、偏身运动和(或)感觉障碍的患者应考虑到病变有可能在脑桥。[Objective] To investigate clinical presentation of pontine infarctions mimicked cerebral hemisphere infarctions,and to analyse the causes of bias in localization diagnosis.[Methods] We analysed 18 patients in a retrospective study within 2 years.[Results] There were motor weakness of the limbs and dysarthria in 16 patients,dizziness after acute stroke onset in 5 patients.When physical examination,contralateral hemiplegia on the infarct focus were in 16 patients,contralateral central facial and tongue paresis on the infarct focus in 17 patients,dysarthria in 16 patients,nystagmus in 3 patients,which being non-continuity.All the lesions were evaluated with the use of MRI.[Conclusions] MRI perfomed at early stage may confirm the diagnosis for pontine infarct mimicked cerebral hemisphere in some clinical findings.When patients complain dysarthria or dizziness and hemiplegia after srtoke onset,we should consider them suffering from the possibility of pontine infarct.
