A 23-year-old woman presented with sudden headache, personality changes and seizure. After neurological assessment, limbic or herpes encephalitis was provisionally diagnosed and treated with intravenous immunoglobulin, acyclovir and steroids. The patient had progressive severe neurological symptoms, requiring prolonged intubation and mechanical ventilation. An anti-NMDAR antibody test revealed positive in serum and cerebrospinal fluid at 3\u2005weeks of admission. Pelvic ultrasound examination and CT scan revealed bilateral small ovarian teratomas. Bilateral ovarian cystectomy was performed by open surgery. The patient showed rapid improvement and no longer needed intubation 2\u2005days after the operation. In conclusion, we described a catastrophic case of ovarian teratoma-associated encephalitis with delayed diagnosis but rapid recovery after ovarian cystectomy. This information can probably be helpful to neurologists and gynaecologists.\n                  <\/jats:p>","DOI":"10.1136\/bcr-2016-216484","type":"journal-article","created":{"date-parts":[[2016,8,10]],"date-time":"2016-08-10T12:06:27Z","timestamp":1470830787000},"page":"bcr2016216484","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Rapid recovery from catastrophic paraneoplastic anti-NMDAR encephalitis secondary to an ovarian teratoma following ovarian cystectomy"],"prefix":"10.1136","volume":"2016","author":[{"given":"Charuwan","family":"Tantipalakorn","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Chiang Mai University, Chiang Mai, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atiwat","family":"Soontornpun","sequence":"additional","affiliation":[{"name":"Medicine (Neurology unit), Chiang Mai University, Chiang Mai, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tip","family":"Pongsuvareeyakul","sequence":"additional","affiliation":[{"name":"Department of Pathology, Chiang Mai University, Chiang Mai, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theera","family":"Tongsong","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Chiang Mai University, Chiang Mai, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2016,8,10]]},"reference":[{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(97)06208-9"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.1997.tb00227.x"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.3","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21050"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.4","doi-asserted-by":"publisher","DOI":"10.1007\/s11060-007-9372-9"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.5","doi-asserted-by":"crossref","first-page":"1723","DOI":"10.3892\/etm.2015.2344","article-title":"Complete recovery from paraneoplastic anti-NMDAR encephalitis associated with a small ovarian teratoma following a laparoscopic salpingo-oophorectomy: a case report","volume":"9","author":"Imai","year":"2015","journal-title":"Exp Ther Med"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.6","doi-asserted-by":"publisher","DOI":"10.1007\/s12013-014-0302-0"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.7","doi-asserted-by":"publisher","DOI":"10.1186\/s12871-015-0134-5"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.8","doi-asserted-by":"publisher","DOI":"10.1186\/s13023-014-0157-x"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.9","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21756"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.10","doi-asserted-by":"crossref","first-page":"540","DOI":"10.1016\/S0026-895X(25)10028-X","article-title":"N-methyl-D-aspartate receptors: different subunit requirements for binding of glutamate antagonists, glycine antagonists, and channel-blocking agents","volume":"45","author":"Lynch","year":"1994","journal-title":"Mol Pharmacol"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.11","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(08)70224-2"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.12","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(10)70253-2"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.13","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2007.136473"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.14","doi-asserted-by":"publisher","DOI":"10.1159\/000353982"},{"key":"2025082702513178000_2016.aug10_1.bcr2016216484.15","doi-asserted-by":"publisher","DOI":"10.1097\/PGP.0b013e31824a1de2"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2016-216484","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T09:51:38Z","timestamp":1756288298000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2016-216484"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,8,10]]},"references-count":15,"alternative-id":["10.1136\/bcr-2016-216484"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2016-216484","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,8,10]]}}}
