Aseptic Meningitis and Papillary Edema: Uncommon Presentation of Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease (MOGAD)

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is an autoimmune disease characterized by central nervous system demyelination. We report a case of prolonged aseptic meningitis in which anti-MOG antibodies were subsequently detected. In addition, we review previously reported cases of MOGAD that initially presented with symptoms of meningitis. MOGAD with meningitis without neurological symptoms or parenchymal brain lesions was rare and characterized by high cerebrospinal fluid (CSF) opening pressures.
