Myelin Oligodendrocyte Glycoprotein (MOG) antibody-associated meningoencephalitis due to Mycoplasma pneumoniae infection

Abstract

ABSTRACT Although myelin oligodendrocyte glycoprotein (MOG) antibody-associated disorders include a wide spectrum of syndromes, manifestations with meningoencephalitis symptoms due to M. pneumoniae infection were quite infrequent. We admitted an 8-years-old girl who presented with recurrent fever accompanied by headache and mild cough, her Cerebral spinal fluid polynucleated cells was elevated and progressively higher, her cranial MRI showed meningeal enhancement initially and multiple intracranial lesions later, serum M. pneumoniae-IgM and MOG-IgG were positive, she was diagnosed with MOG-IgG associated meningoencephalitis due to M. pneumoniae infection, the treatment consisted of intravenous immunoglobulin, glucocorticoid, and erythromycin, then she was completely recovered.
