 A 19-year-old woman was admitted to our hospital because of symptoms of agitation and monology. She gradually developed stuporous;this was followed by impaired consciousness with hypersalivation, hyperhidrosis, nuchal rigidity, involuntary movement, fluctuating blood pressure, and tachycardia. She eventually developed respiratory failure. Thereafter, the symptoms rapidly improved. MRI revealed no cerebral abnormalities, and examination of the cerebrospinal fluid indicated only a slight increase in the lymphocyte count. Electroencephalography revealed generalized bursts of high-voltage slow waves. Single-photon emission computed tomography revealed an extensive decrease in the relative blood flow. MRI of the abdomen revealed the presence of an ovarian teratoma. The clinical characteristics in the present case were consistent with those of acute reversible limbic encephalitis, acute juvenile female non-herpetic encephalitis, and anti-NMDAR encephalitis.
