摘要： 目的探讨临床脑桥旁正中梗死误诊的原因。方法对2008～2010年本院住院的20例误诊为大脑半球病变的脑桥旁正中梗死的临床症状、体征及超早期头颅CT平扫，48h内的头颅MR影像学特点及相关辅助检查进行回顾性分析。结果20例误诊为大脑半球病变的脑梗死，经MR检查确诊为脑桥旁正中动脉梗死。结论脑桥旁正中梗死临床常见，但易漏诊，早期行MR有助于确诊。对早期有一过性头晕，临床表现为一侧偏瘫患者，要注意病灶有可能在脑干。

Abstract: Objective To explore the reasons for misdiagnosis of paramedian pontine infarction. Methods 20 cases of paramedian pontine infarction which were misdiagnosed as cerebral hemisphere lesions were collected. The clinical manifestations, signs, and hyperacute cerebral CT scans, MR imaging characteristics within 48 h and other auxiliary examinations were analyzed retrospectively. Results 20 cases which were misdiagnosed as cerebral hemisphere lesions were confirmed as paramedian pontine infarction by MR. Conclusion Paramedian pontine infarction is rather common during daily clinical work, but often misdiagnosed. Early MR examination is helpful to correct diagnosis. For patients who have hemiplegic paralysis and transient dizzy symptoms during early phases, it is specially noticed that the lesions may be located in brain stem.
