Myelin oligodendrocyte glycoprotein (MOG), a member of the immunoglobulin (Ig) superfamily, is a protein found exclusively on the outer surface of myelin sheaths and oligodendrocyte membranes. Because of this specific localization, MOG can become a target for both cellular and humoral immune responses in inflammatory demyelinating diseases. Its expression occurs later in postnatal development, making it a key marker for the maturation of oligodendrocytes. Autoantibodies targeting myelin oligodendrocyte glycoprotein (MOG) can result in various autoimmune disorders, including optic neuritis, transverse myelitis, brainstem encephalitis, and acute disseminated encephalomyelitis.In this case report we present a 19 year old male patient presented with complaints of bilateral lower limb numbness with acute urine retention since 1 day.
