Laparoscopic cystectomy of ovarian teratoma in anti-NMDAR encephalitis: 2 case reports

We present 2 case reports of anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis that was successfully treated via laparoscopic ovarian cystectomy. In both cases, resection of an ovarian teratoma resulted in eventual full recovery. Although adnexectomy has been reported for tumor resection in anti-NMDAR encephalitis, we chose ovarian cystectomy to preserve ovarian function. The efficacy of cystectomy is equivalent to that of adnexectomy. This suggests that ovarian adnexectomy may not be necessary in anti-NMDAR encephalitis with ovarian teratoma.
