摘要 目的报道抗LGI1抗体和抗IgLON5抗体双阳性的自身免疫性脑炎病例。方法收集1例自身免疫性脑炎病例的临床表现、影像学、免疫抗体检测资料,结合文献复习进行讨论。结果患者男性,68岁。主要临床表现为记忆力明显减退,反应迟钝,认人不清、胡言乱语,伴有定向力障碍。血清及脑脊液的抗LGI1抗体IgG阳性(滴度均1:10);血清抗IgLON5抗体IgG阳性(滴度1:100)、脑脊液抗IgLON5抗体IgG阳性(滴度1:10)。影像学改变为双侧颞叶内侧、海马异常信号影。给予皮质激素与大剂量丙种球蛋白联合治疗后症状无改善,仍继续加重。结论自身免疫性脑炎临床特征不典型,行自身免疫性脑炎相关多抗体检测可进一步协助明确诊断;文中报道的抗LGI1抗体及抗IgLON5抗体双阳性的自身免疫性脑炎病例的预后不佳。
