摘要
目的 :分析Wallenberg综合征的临床和MRI关系。方法 :采用临床和MRI对比分析的方法 ,分析Wallen berg综合征。结果 :延髓上部病灶多为背外侧部梗塞或出血 ,延髓下部病灶多为外侧浅层梗塞 ,前者以明显吞咽困难、声音嘶哑、软腭麻痹和咽反射消失为主 ,后者以明显眩晕、眼球震颤和步态共济失调为主 ,二者均有恶心或呕吐、Horner征和面部及对侧颈以下的痛觉减退。结论 :MRI可以帮助阐明Wallenberg综合征的解剖和临床表现的关系。
OBJECTIVE:To analyse correlation between clinical findings and magnetic resonance imaging (MRI) results of Wallenberg's lateral medullary syndrome (WLMS).METHODS:WLMS was analysed by comparing clinical findings with MRI results.RESULTS:The upper medullary lesions were mostly posterolateral medullary infarctions or hemorrhage and were associated with more severe dysphagia, hoarseness, soft palatina parlysis and pharyngeal areflexia. Whereas the lower medullary lesions, were mainly the lateral -superficial medullary infarctions, and were correlated with more marked vertigo,nystagmus and gait ataxia. And nausea or vomiting, Horner sign, and facial and contralateral hemibody below neck hypoalgesia were common regardless of the lesion location.CONCLUSION:MRI findings help to elucidate correlation between anatomy and clinical manifestation of WLMS.
