Abstract

N-methyl-D-aspartate receptor (NMDAR) encephalitis is a rare antibody-mediated autoimmune encephalitis often associated with an ovarian teratoma in adolescent females. Here we present a 17-year-old girl with only and unusual psychiatric symptoms as part of her NMDAR encephalitis in combination with a very small ovarian teratoma suspected by magnetic resonance (MR) imaging and finally histologically confirmed. We further review the literature of NMDAR encephalitis in combination with an ovarian teratoma and discuss the recommended radiological workup in children with a suspected ovarian tumor.
