Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a type of limbic encephalitis that is resulted by an autoimmune processes; it is a rare autoimmune encephalitis caused by the NMDA receptor antibody secreted by all kinds of tumors. This paraneoplastic syndrome is frequently associated with ovarian teratomas; however, neural cells expressing anti-NMDAR may also be involved in the disease. We report a patient with a case of anti-NMDAR encephalitis associated with an ovarian teratoma, and present a literature review of 16 cases of anti-NMDAR encephalitis in Korean women.
