摘要
目的 :探讨急性播散性脑脊髓炎 ( ADEM)的临床表现与影像学改变的关系。方法 :对 9例确诊的 ADEM患者的 MRI或 CT改变的部位、范围、数量与临床症状及体征进行对照分析。结果 :ADEM的 MRI改变为双侧皮质下白质或脊髓的多灶性、大小不等的长 T1 长 T2 异常信号 ,CT改变为低密度灶 ,病情轻重与病变部位、大小有关 ,而与病变数量无明显相关。结论 :对有精神行为异常、意识障碍、瘫痪等神经系统广泛受损 ,且影像学改变为大脑白质多灶性损害者 ,应高度警惕 ADEM的可能。
Objective:To explore the relationships between the clinical features and the imaging characteristics of ADEM.Method:The location, size and number on CT and MRI and their clinical features of nine patients diagnosed the ADEM were analyzed .Results:Using MRI, the image lesion was defined by multifocal and various sized abnormal picture of long T1 and long T2 in the bilateral sub cortical white. Using C T, the image lesion is defined by the lower density. The clinical seriousness of patients correlated to the location and size of abnormal image but not to the number of the abnormal image.Conclusion:If a patient developed symptom of having been widely damaged in neural system and the abnormal image lesion of multifocal subcortical white,ADEM must be taken into concern.
