经MRI确诊的延髓背外侧综合征

Dorsolateral Medullary Syndrome Diagnosed by MRI

应用MRI研究延髓背外侧综合征。具有本病临床表现的11例患者均行头颅CT及MRI检查。眩晕、呕吐、眼球震颤、声音嘶哑、同侧面部及对侧肢体痛温觉障碍、同侧软腭麻痹、同侧肢体共济失调、同侧Horner征是最常见的临床特征。MRI显示一侧延髓背外侧梗塞10例,延髓背外及腹外侧梗塞1例,合并同侧小脑梗塞2例。CT均未发现延髓及小脑病灶。MRI为目前研究延髓背外侧综合征最佳手段,小脑区梗塞不容忽视。

To study Dorsolateral Medullary Syndrome with MRI. 11 Patients with this syndrome were performed head CT and MRI. Demonstrated vertigo, nausea-emesis, nystagmus, hoarseness, numbness either of the ipsilateral face and contralateral body, ipsilateral palatal paralysis, ipsilateral ataxia. Homer's syndrome were the most frequent characteritics of Dorsolateral Medullary Syndrome. MRI showed a dorsolateral Medullary infarction in 10 cases, a dorsolateral and abdominolateral medullary infarction in 1 case, a cerebellar infarction in 2 cases. CT scan did not show any medullary and cerebellar infarction in all patients. MRI is the best way at present to study Dorsolateral Medullary Syndrome. Cerebellar infarction must be alerted by clinicain.
