摘要
目的为了探讨视神经炎与多发性硬化的关系。方法分析28例视神经炎患者的头颅磁共振(MRI)及体感诱发电位(SEP)检查情况。结果(1)头颅MRI扫描异常率为32.1%,病灶呈多发性,主要分布在侧脑室旁、半卵圆中心,长T2信号,少数合并长T1信号。(2)SEP中枢传导异常率为42.9%,下肢异常多于上肢,单侧异常多于双侧。(3)发病两次及两次以上,脊髓受累机会增加。
Object In order to explore the relationship between optic neuritis and multiple sclerosis.Methods Brain magnetic resonance imaging(MRI) and limb somatosensory evoked potential(SEP) were observed in 28 patients with optic neuritis.Results (1) Brain MRI showed 32.1% abnormalities in white matter regions.The foci were multipe,they distributed at lateral periventricular regions and centra semiovale.all showed long T_2 signals but long T_1 signals accompanied partly.(2) SEP suggested 42.9% abnormalities of central conduction,more abnormalities from the legs than arms and more unilateral abnormalities than bilateral.(3)The onset of disease twice or over twice,the injury of the spinal cords increased. Conclusion The optic neuritis with more subclinical lesions might be one of the clinical types of multiple sclerosis.
