Sumario:Autoimmune encephalitis with antibodies against neuronal cell surface antigens is a group of neuropsychiatric disorders, with anti-N-methyl D-aspartate (NMDAR) encephalitis being one of them. We report a case of a young male patient who presented with complaints of seizures associated with fever, rapidly progressing memory loss, and choreoathetoid movements for 1 month. His serum was strongly positive for anti-NMDAR receptor antibodies. F-18 fluorodeoxyglucose positron-emission tomography/computed tomography for the brain revealed hypermetabolism involving bilateral basal ganglia and bilateral mammillary bodies associated with hypometabolism in bilateral occipital lobes.
