Clinical analysis of five case reports of ovarian teratoma with anti-N-methyl-D-aspartate receptor encephalitis

摘要

We have collected the data of five patients with ovarian teratoma and anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis admitted to the Southern Hospital of Southern Medical University from June 2014 to December 2017, we found that all of them started with psychiatric symptoms, four had autonomic nervous system dysfunction, while all of them exposed to abnormal brain and pelvic imaging, four patients required mechanical ventilation to assist breathing during the hospital stay. The serum anti-NMDAR antibodies were positive in five patients. After immunotherapy and surgery, all patients showed favorable prognosis. Pathology: four mature teratomas and one immature teratoma. In conclusion, patients with ovarian teratoma with anti-NMDAR encephalitis often begins with neurological and psychiatric symptoms, it is easy to be misdiagnosed due to the lack of overt symptoms, while the early detection and tumor resection combined with immunotherapy will win favorable prognosis.
