Abstract: Abstract: Anti-N-methyl-D-aspartate receptor encephalitis, which is always associated with germ cell tumors such as teratoma, is an autoimmune encephalitis discovered recently. The pathogenesis is high likely related to anti-N-methyl-D-aspartate antibody, which have obstruct the transmission of neural signals. Its clinical manifestation is diverse and the treatment combines immunotherapy with tumor resection. The prognosis is also good. This review mainly introduce the researches on anti-N-methyl-D-aspartate receptor encephalitis associated with ovarian teratoma to improve the awareness of clinician on this recent discovered disease.
