Several cases of myelin oligodendrocyte glycoprotein (MOG) antibody-associated encephalitis have been reported after coronavirus disease 2019 (COVID-19). In this case, the patient presented with focal status epilepticus with impaired awareness, auditory hallucinations, and incoherent speech after COVID-19. Brain magnetic resonance imaging revealed no specific findings. Cerebrospinal fluid results showed pleocytosis and MOG antibody testing confirmed anti-MOG antibody with live cell-based fluorescence-activated cell sorting assay. The patient was diagnosed with MOG antibody-associated autoimmune encephalitis and treated with intravenous immunoglobulin, rituximab, and tocilizumab. This case occurred presumably due to auto-antibody production following COVID-19.
2019冠状病毒病（COVID-19）后已有多例髓鞘少突胶质细胞糖蛋白（MOG）抗体相关脑炎的报道。在本病例中，患者在感染COVID-19后出现伴有意识障碍、幻听和言语紊乱的局灶性癫痫持续状态。脑部磁共振成像未发现特异性表现。脑脊液检查结果显示细胞增多，基于活细胞的荧光激活细胞分选试验的MOG抗体检测证实存在抗MOG抗体。该患者被诊断为MOG抗体相关自身免疫性脑炎，并接受了静脉注射免疫球蛋白、利妥昔单抗和托珠单抗治疗。该病例可能是由于COVID-19后自身抗体产生所致。
