Rare nervous system involvement in an anti-myelin oligodendrocyte-positive case: spinal leptomeningeal involvement

Anti-myelin oligodendrocyte (MOG)-positive cases have a variable clinical presentation. MOG autoantibodies are associated with acute disseminated encephalomyelitis, multiple sclerosis, clinically isolated syndrome, neuromyelitis optica, optic neuritis, and transverse myelitis. Our patient had bilateral neuritis tetraparesis. Cranial magnetic resonance imaging (MRI) showed leptomeningeal contrast involvement enhancement in all cranial nerve nuclei. Spinal MRI revealed enhancement, contrast-enhancing lesion was found the cervical spinal cord. This case is worth presenting because rare anti-MOG-positive patients.
