Refractory MOG-Associated Demyelinating Disease in a Pediatric Patient

Background: MOG antibody associated demyelinating disease (MOGAD) is a newly described autoimmune disorder that presents with monophasic or multiphasic demyelination in children. Case: We report a case of MOGAD that was refractory to current treatment algorithms and required rapid escalation of immunotherapy to achieve disease control. Conclusion: This case helps to further expand the phenotype of MOGAD and emphasizes the need to consider MOGAD in patients presenting with focal neurologic deficits, altered mental status, and/or seizures.
