Background: Myelin-oligodendrocyte-glycoprotein (MOG)-IgG-positivity in patients with typical MS lesions on MRI may lead to diagnostic/therapeutic uncertainty. Objective and Methods: We reviewed reports of cases with MS phenotype on MRI and MOG-IgG-positivity published in Pubmed between 01/2012-06/2021. Results: Sixteen patients were included (median age [range], 37,5 [25-66] years; 60% female). Three patients initially tested negative for MOG-IgG. Disease course was: relapsing-remitting, 10; or progressive, 6. Intrathecal IgG-synthesis was common (79%). Low and high-efficacy MS-targeted agents prevented relapses in 30% and 100%, respectively. None of the patients showed resolution of MRI T2-lesions over time. Conclusions: MOG-IgG-positivity is unlikely to alter the expected treatment response and outcomes in patients with otherwise typical MS phenotype on MRI.
