Anti-myelin oligodendrocyte glycoprotein antibody-associated encephalitis with cortical hyperintensity and pathologically confirmed extensive demyelination

Recently, unilateral cortical fluid-attenuated inversion recovery-hyperintense lesions in anti-myelin oligodendrocyte glycoprotein (MOG)-associated encephalitis with seizures (FLAMES) have been revealed as one of the clinical types of anti-MOG antibody-associated diseases (MOGAD).
