目的 探讨视神经脊髓炎 (NMO)与多发性硬化 (MS)的区别。方法 对 32例 NMO患者的临床表现、CT与 MRI检查结果进行分析。结果 2 4例 (75 % ) NMO患者有多次 (平均 2 .9次 )缓解复发 ,复发时症状仅限于视神经和 /或脊髓 ;头颅 CT和 MRI检查均未发现新的脱髓鞘斑块。结论 NMO与 MS有所区别 ,前者多次复发 ,病变仅局限于视神经和 /或脊髓部位。支持 NMO是一个独立疾病的观点。
Objective To explore the difference between optic neuromyelitis (NMO) and multiple sclerosis (MS). Methods 32 cases of NMO patients with clinical manifestations, CT and MRI examination results were analyzed. Results Twenty-four (75%) NMO patients had multiple (mean, mean 2.9) remissions with symptoms that were limited to the optic nerve and / or spinal cord at the time of recurrence; no new demyelinating plaques were found on CT and MRI scans. Conclusion NMO and MS are different, the former repeated many times, the lesion is limited to the optic nerve and / or spinal cord site. Support NMO is an independent disease point of view.
