Objectives
Narrative objectives1
Anti-N-methyl-D-aspartate (NMDA)-receptor (R) encephalitis was initially described by Dalmau and colleagues in 2007 when they discovered the anti-NMDAR antibody in a set of young females who had an array of neurological symptoms in association with ovarian teratomas. The typical clinical picture presents with neuropsychiatric symptoms, seizures, dyskinesias, autonomic dysregulation, and dyspnea. The association of ovarian teratoma and anti-NMDAR encephalitis is a serious and potentially fatal disorder that occurs in young women and is thought to be paraneoplastic, in particular due to the rapid clinical improvement after the treatment for the teratoma. However, operative methods (open laparotomy or laparoscopic surgery / cystectomy or ovariectomy) for ovarian teratomas are not uniform in Japan. Objectives are to analyze prevalence and outcome of this association, and increase awareness over this disorder. This study will investigate the timing of operation, surgery method (open laparotomy or laparoscopic surgery / ovarian cystectomy or oophorectomy) for ovarian teratoma in young patients with this encephalitis, and the short-term outcome of the related symptoms after the operation, and will provide practical guidance of the rare disorder for the general gynecologist.
