Anti-N-methyl-D-aspar tate receptor encephalitis associated with ovarian teratoma: A case report

We report a rare case of a young woman with anti-N-Methyl-D-Aspartate receptor (NMDAR) encephalitis, who developed psychiatric symptoms, dyskinesias, hypoventilation, hypersalivation and seizures. Serial analysis of antibodies to NR1/NR2B heteromers of the NMDAR was positive on the patient's serum and cerebrospinal fluid (CSF). Removal of an ovarian teratoma after intravenous immunoglobulin and corticosteroid therapy resulted in a prompt neurological response.
