Autoimmune encephalitis with acute presentation masquerading as viral encephalitis

Encephalitic syndromes typically manifest with fever, altered sensorium and seizures. Viral etiology
accounts for the significant proportion of cases especially with acute febrile illness. Here we report a
middle aged female with anti NMDAR encephalitis with acute presentation mimicking viral encephalitis.
She had good clinical and radiological improvement with immunosuppressive therapy.
