Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is the most common form of paraneoplastic encephalitis that is associated with teratomas. Because removal of the tumor leads to better clinical outcomes, determining the location of teratomas is essential. The authors report two cases of anti-NMDA receptor encephalitis with a small ovarian teratoma that could not be detected by usual imaging. Both cases had the diagnosis confirmed laparoscopically.
