OBJECTIVE: To investigate the clinical and MRI features of myelin oligodendrocyte glycoprotein (MOG) antibody-positive cerebral cortical encephalitis. METHODS: To summarize the clinical manifestations, magnetic resonance imaging (MRI) features, and diagnosis and treatment of two children diagnosed with MOG antibody-positive cortical encephalitis in our hospital, and to analyze all of the literature on MOG antibody-positive associated cerebral cortical encephalitis published in the last 10 years. RESULTS: A total of 24 patients, 20 adults, and 4 children were included. The main symptoms of all observed patients were as follows: seizures 20/24 (83%), headache 18/24 (75%), fever 13/24 (54%), and increased cell number in cerebrospinal fluid 22/24 (92%). The main radiological sign was enhanced FLAIR signal in cortical 24/24 (100%), including enhanced fluid-attenuated inversion recovery (FLAIR) signal in unilateral cortical 20/24 (83%). CONCLUSIONS: The clinical manifestations of MOG antibody-positive cerebral cortical encephalitis are complex and varied, and long-term follow-up is needed to clarify the prognosis and recurrence, providing reference for the clinical treatment.
