摘　　要：目的探讨无典型症状桥脑梗死的临床及影像学特点,并分析误诊原因。方法对我院头颅MRI检查确诊但首诊误诊的42例桥脑梗死的临床资料进行回顾性分析。结果本组42例均无桥脑梗死典型的交叉性瘫痪,其中34例入院误诊为大脑半球梗死,8例误诊为椎基底动脉供血不足,72 h内查头颅MRI均检出CT未检出的桥脑梗死灶,确诊为桥脑梗死,予活血、抗血小板聚集等治疗后症状均明显好转。结论无典型症状的桥脑梗死临床较易误诊,早期行MRI检查有助于明确诊断。Objective To explore the clinical and imaging characteristics of bridge cerebral infarction without typical symp- toms in order to analyze the misdiagnosed cause. Methods Retrospective analysis of clinical data of 42 patient~,; in our hospital with bridge cerebral infarction who were diagnosed by MRI were made. Results 42 patients had no typical cross paralysis, among whom 34 patients were misdiagnosed as having interhemispheric cerebral infarction, 8 were misdiagnosed as having ver^ebrobasilar ischemia. The patients were misdiagnosed by head CT but was diagnosed with focus＇ of bridge cerebral infarction by MRI in 72 hours. The patients＇symptoms were alleviated after improvement of blood circulation and antiplatelet. Conclusion Bridge cerebral infarction is easy to be misdiagnosed without typical symptoms, and MRI detection in early stage can help final diagnosis.
