Myelin oligodendrocyte glycoprotein-antibodies (MOG-IgG) are associated with acquired inflammatory demyelinating syndromes, seen predominantly in children and young adults. The overlapping clinical and radiological features of the heterogenous spectrum of demyelinating central nervous system (CNS) diseases makes the detection of MOG-IgG antibodies important for prognosis and treatment decisions. Herein, we describe the occurrence of MOG-IgG associated disease presenting as acute disseminated encephalomyelitis (ADEM), with spinal MRI findings of centrally located long cord lesion in a 14-month old child.
