摘要
患者男,60岁,主诉性格改变、嗜睡5个月,加重伴视力下降2个月。患者5个月前出现情绪烦躁、易怒、言语减少、嗜睡,伴间断性头晕,未予特殊诊治。2个月前出现左眼视力下降,脾气更加暴躁,反应较前明显迟钝。头部增强MRI示左侧颞叶内侧、左侧基底节区、胼胝体、视交叉多发异常信号。外院曾考虑视神经脊髓炎(neuromyelitis optica,NMO)谱系疾病,予泼尼松及静脉丙种球蛋白治疗,未见好转。20余天前右眼视力下降,双眼均有胀痛感,头晕、嗜睡加重。复查头部增强MRI提示:左侧颞叶内侧、胼胝体、视交叉多发异常信号,T1加权成像(weighted imaging,WI)呈低信号,T2WI呈稍高信号,T2液体衰减反转恢复序列(fluid attenuated inversion recovery,FLAIR)呈高信号,信号较均匀,增强明显均匀强化(图1)。
