AbstractUnder the umbrella of pediatric-acquired demyelinating syndromes, there is a multitude of disorders, including optic neuritis, transverse myelitis, acute disseminated encephalomyelitis (ADEM), multiple sclerosis (MS), and neuromyelitis optica spectrum disorders (NMOSD). Due to overlapping clinical and magnetic resonance imaging (MRI) features, it can be challenging to provide an accurate diagnosis. In view of therapeutic and prognostic implications, an early and reliable diagnosis is however of utmost importance. Recent studies of myelin oligodendrocyte glycoprotein (MOG) identify MOG, as a promising target for antibody-mediated demyelination and a biomarker for a relatively benign and non-MS disease course. We describe the clinical and MRI presentation of five children presenting with an acute, severe central nervous system inflammatory disease involving the brain and spinal cord, all of whom were positive for MOG-IgG antibody. Encephalopathy was uncommon at presentation and all had quick resolution of symptoms with intravenous steroid and intravenous immunoglobulin (IVIG) treatment. All patients recovered well, and have been treated with IVIG to potentially prevent relapses. Georg Thieme Verlag KG Stuttgart · New York.
