Neurology:慢性炎症性神经病变存在脑膜增强

2017-03-21 MedSci MedSci原创

目的:为了评估2个学术研究医院,多发性硬化症(MS)与一些炎症和非炎症神经疾病患者,头颅MRI增强T2液体衰减反转恢复序列(FLAIR)成像显示脑膜增强(LME)特异性和发生率。方法:评估非MS或嗜神经病毒感染的254例患者3T增强 T2-FLAIR图像是否存在脑膜增强。根据临床诊断,患者被分为:(1)非MS的炎症性神经系统疾病;(2)非炎症性神经系统疾病;(3)人类T淋巴细胞白血病病毒(HTLV

目的:为了评估2个学术研究医院,多发性硬化症(MS)与一些炎症和非炎症神经疾病患者,头颅MRI增强T2液体衰减反转恢复序列(FLAIR)成像显示脑膜增强(LME)特异性和发生率。

方法:评估非MS或嗜神经病毒感染的254例患者3T增强 T2-FLAIR图像是否存在脑膜增强。
根据临床诊断,患者被分为:(1)非MS的炎症性神经系统疾病;(2)非炎症性神经系统疾病;(3)人类T淋巴细胞白血病病毒(HTLV)感染;(4)HIV感染;(5)健康志愿者。

结果: 非MS患者中56 / 254例存在LME,MS病例中有74 / 299(25%)存在LME。非MS炎症性神经系统疾病存在LME(18/51例,35%)的频率是非炎症性神经疾病(3/38、8%)和健康志愿者(5/66、8%)。HTLV感染的患者LME的发生率最高(17/38例,45%),特别是在HTLV相关脊髓病(14/25例,56%)。LME也经常发生在HIV感染(13/61例,21%)的患者中。不同于MS,LME与非MS炎症神经疾病(HTLV和HIV感染)中脑和皮质容积不相关。

结论:尽管MS的发病机制和皮质病理相关性,LME不是MS特异的,非MS炎症神经神经疾病尤其是HTLV相关脊髓病也常存在LME。总的来说,这进一步证明,LME与炎症相关的血脑屏障破坏和局灶性疤痕相关。
