Myelin oligodendrocyte glycoprotein (MOG) antibodies have been identified in central nervous system inflammatory demyelinating disorders (MOG antibody disease), inclusive of optic neuritis, transverse myelitis, or acute disseminated encephalomyelitis. The association of MOG antibodies with combined central and peripheral demyelination (CCPD) is not clear. It has been reported in a few cases where MOG antibodies were detected in the serum of patients with chronic inflammatory demyelinating polyneuropathy. However, multifocal motor neuropathy with MOG antibodies is extremely rare. We present a patient who had clinical, neurophysiological, radiological, and biochemical findings that support the diagnosis of CCPD (multifocal motor neuropathy and cord lesion) with MOG antibodies. The patient was treated with a combination therapy of intravenous immunoglobulins plus high-dose methylprednisolone, which resulted in significant improvement.
Keywords: chronic inflammatory demyelinating polyneuropathy; combined central and peripheral demyelination; demyelinating disorders; multifocal motor neuropathy; multiple sclerosis; myelin oligodendrocyte glycoprotein (mog) antibodies.
