BACKGROUND Anti-N-methyl-D-aspartate receptor(anti-NMDAR)encephalitis is a rare autoimmune disorder.The symptoms of anti-NMDAR encephalitis include behavioral problems,speech problems,psychosis,seizures,and memory deficits,among others.However,laryngospasm is rare.We present the case of a patient with anti-NMDAR antibodies and severe laryngospasms.CASE SUMMARY The patient was a 15-year-old female with normal psychomotor development.She was initially admitted to our neurological intensive care unit with seizures.She received anti-epilepsy treatment,and the seizures disappeared.However,2 wk later,she developed behavioral problems and speech impairment.Then,she developed severe laryngospasms,which were treated with intubation and a tracheotomy.Antibodies against the NMDAR were detected in the patient’s cerebrospinal fluid.Therefore,she was diagnosed with anti-NMDAR encephalitis.In addition,she received intravenously administered immunoglobulins,and methylprednisolone was administered.The patient’s symptoms gradually improved,and she was discharged from our hospital.Approximately 9 mo later,the patient could speak sentences,walk independently,and carry out activities of daily living independently.Through our case report,we highlighted laryngospasm as an uncommon presentation in patients with anti-NMDAR encephalitis.CONCLUSION Laryngospasm may be an uncommon clinical manifestation of anti-NMDAR encephalitis.
