MOG autoimmunity mimicking CLIPPERS syndrome: Case report and literature review.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is an inflammatory syndrome characterized by the predominant involvement of the pons, the cerebellum and the spinal cord with a distinct corticosteroid responsiveness. To date, several cases of neurological disorders with a CLIPPERS-like phenotype have been described, including patients with Immunoglobulin G (IgG) antibodies binding to myelin oligodendrocyte glycoprotein (MOG). We herein report the case of a man with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) fulfilling the diagnostic criteria for probable CLIPPERS and a literature review of CLIPPERS-mimicking patients with MOG-IgG.
