目的：探讨ＣＴ，ＭＲＩＢＡＥＰ对脑干病变诊断的敏感性及ＢＡＥＰ与脑干病损严重程度和预后的关系。方法：对３２例脑干病变的患者同时进行了ＣＴ、ＭＲＩ及ＢＡＥＰ检查，同时对患者进行格拉斯哥昏迷计分（Ｇｌａｓｇｏｗｃｏｍａｓｃｏｒｅ，ＧＣＳ）及神经功能缺损评从（ＳＳＳ）。根据ＢＡＥＰ检查结果分为３组：Ⅰ组：ＢＡＥＰ正常组；Ⅱ组ＢＡＥＰ异常或双侧不对称，但各波存在；Ⅲ组：除Ⅰ波外，其余各波消失。病后３月对患者进行预后评价。结果：脑干病变ＣＴ阳性率５３．１３％，ＭＲＩ阳性率９０．６２％，ＢＡＥＰ阳性率８４．３８％。ＭＲＩ及ＢＡＥＰ阳性率高于头颅ＣＴ，有显著性差异，Ｐ＜０．０５。Ⅰ组及Ⅱ组患者ＧＣＳ计分高于Ⅲ组，ＳＳＳ评分低于Ⅲ组，Ⅲ组的患者均预后不良，与Ⅰ组及Ⅱ组比较有显著差异ｐ＜０．０５。结论：ＭＲＩ和ＢＡＥＰ对脑干病变异常率较高，若同时进行ＭＲＩ和ＢＡＥＰ检查阳性率达１００％；ＢＡＥＰ是判断脑干病变严重程度及预后较为可靠的指标。
Objective: To investigate the sensitivity of CT and MRIBAEP in the diagnosis of brainstem lesions and the relationship between BAEP and the severity and prognosis of brain stem lesions. Methods: CT, MRI and BAEP were performed in 32 patients with brain stem lesions. Glasgow coma score (GCS) and neurological deficit score (SSS) were also measured. BAEP examination results were divided into 3 groups: Ⅰ group: BAEP normal group; Ⅱ group BAEP abnormal or bilateral asymmetry, but the wave exists; Ⅲ group: except Ⅰ wave, the other waves disappear. Patients were evaluated for prognosis in March after illness. Results: The positive rate of CT in brain stem lesions was 53.13%, the positive rate of MRI was 90.62%, and the positive rate of BAEP was 84.38%. MRI and BAEP positive rate higher than the head CT, there was a significant difference, P <0.05. The scores of GCS in group Ⅰ and group Ⅱ were higher than those in group Ⅲ, and the scores of SSS in group Ⅲ were lower than those in group Ⅲ. The patients in group Ⅲ had poor prognosis. There were significant differences between group Ⅰ and group Ⅱ (p <0.05). Conclusion: MRI and BAEP have a higher rate of abnormalities in brain stem lesions. The positive rate of MRI and BAEP is 100% at the same time. BAEP is a reliable indicator to judge the severity of brain stem disease and prognosis.
