Anti-NMDA receptor encephalitis with atypical brain changes on MRI.
A young girl with antibodies to the N-methyl-D-aspartate receptor presented with a clinical syndrome suggestive of dyskinetic encephalitis lethargica with neuropsychiatric features at presentation, movement disorder, mutism, sleep disorder, and seizures. Persistent lesions in the white matter and pons were observed in magnetic resonance imaging of the brain, findings that have not been described previously in N-methyl-D-aspartate receptor antibody encephalitis.
