Similar cases were subsequently reported and referred to as FLAIR-hyperintense lesions in anti-MOG-associated encephalitis with seizures (FLAMES) [3, 4].Fujimori et al. then found that some patients presented with bilateral cortical encephalitis (CE), expanding the spectrum of FLAMES [5].MOG antibody-associated cortical encephalitis (MOGCE) was proposed as a new spectrum, including both unilateral and bilateral CE [6]. The gene discussed is MOG; the disease is encephalitis.
