目的:探討復(fù)發(fā)型視神經(jīng)脊髓炎(relapsing neuromyelitis optica,R-NMO)與復(fù)發(fā)型多發(fā)性硬化(relapsingremitting multiple sclerosis,RRMS)患者視神經(jīng)的MRI影像表現(xiàn)。方法:對臨床滿足R-NMO最新Wingerchuk等制定的診斷標(biāo)準(zhǔn)及滿足最新McDonald診斷標(biāo)準(zhǔn)的RRMS患者,進(jìn)行腦部、脊髓及視神經(jīng)的掃描,并將兩組復(fù)發(fā)型患者視神經(jīng)MRI表現(xiàn)特點(diǎn),與32位健康自愿者進(jìn)行對照研究。同時回顧性分析患者的VEP檢查結(jié)果。結(jié)果:41例R-NMO患者M(jìn)RI檢查顯示患者均有單側(cè)或雙側(cè)視神經(jīng)鞘膜腔信號明顯增高,呈“軌道樣”改變,22例患者(53.7%)伴有視神經(jīng)增粗,或(和)扭曲,17例(41.5%)可看視神經(jīng)內(nèi)點(diǎn)狀高信號表現(xiàn)。隨著病程的延長,15例(36.6%)MRI上可見單側(cè)或雙側(cè)視神經(jīng)萎縮、變細(xì),甚至扭曲。最終35例(80.5%)視神經(jīng)內(nèi)見到點(diǎn)狀高信號表現(xiàn)。121例RRMS患者中,共81名(66.9%)患者在MRI上見到了視神經(jīng)的異常表現(xiàn),主要表現(xiàn)為單側(cè)或雙側(cè)視神經(jīng)鞘膜腔部分節(jié)段或全段呈“軌道樣”高信號改變,其中23例(28.4%)表現(xiàn)為視神經(jīng)球球后起始段局限性信號增高,視神經(jīng)15例(12.4%)伴有視神經(jīng)的腫脹,但視神經(jīng)萎縮不及R-NMO患者明顯。隨著時間延長,12例(9.9%)可見視神經(jīng)內(nèi)點(diǎn)狀高信號脫髓鞘改變。兩組患者P100峰值延遲時間差異具有統(tǒng)計(jì)學(xué)意義(P lt;0.05)。結(jié)論:MRI可以成為視神經(jīng)炎的首選影像學(xué)檢查方法。兩組患者M(jìn)RI與VEP檢查結(jié)果存在一定的差異性,可以成為鑒別診斷的依據(jù)。
