MRI-Negative Myelitis Associated With Myelin Oligodendrocyte Glycoprotein Antibody Spectrum Demyelinating Disease

Myelin oligodendrocyte glycoprotein is expressed in the central nervous system on the surface of oligodendrocytes and is associated with a broad range of adult and pediatric demyelinating phenotypes. The entire spectrum of clinical and radiologic features of myelin oligodendrocyte glycoprotein antibody spectrum disorder remains to be fully elucidated. We describe the case of a 9-year-old boy with immune-mediated myelitis undetectable by...
