He had positive serum antithyroid antibodies, IgM antibodies against Mycoplasma pneumoniae and human herpesvirus 7 polymerase chain reaction in the cerebrospinal fluid. He was successfully treated with rituximab, after steroids, intravenous immunoglobulin and plasma exchange. The pathophysiology of this disorder may be post-infectious and autoimmune.engAnti-N-Methyl-D-Aspartate Receptor EncephalitisAntibodies, BacterialAntibodies, Monoclonal, Murine-DerivedAntibodies, ViralAutoantibodiesChildHerpesvirus 7, HumanHumansImmunoglobulin MImmunologic FactorsMaleMycoplasma pneumoniaeRituximabHDE INF PEDHDE UCI PEDHDE NEU PEDAnti-N-Methyl-D-Aspartate Receptor Encephalitis with Positive Serum Antithyroid Antibodies, IgM Antibodies Against Mycoplasma Pneumoniae and Human Herpesvirus 7 PCR in the CSFjournal article10.1097/INF.0000000000000408
