Main Article Content
Abstract
Abstract: A previously healthy 30-year old lady presented with 1-day history of high grade fever and drowsiness. Five days prior to
presentation, she developed insomnia and visual hallucinations of seeing unknown faces. Three days prior to presentation, she suffered from 5
episodes of generalized tonic colonic fits. On admission, she had a temperature of 102oF and GCS of 10/15 with no signs of meningeal
irritation, no focal neurological deficit, normal deep tendon reflexes and down-going plantar reflex bilaterally. Her brain MRI scan showed
mild hyper-intense signals in right cerebellum. Her CSF was tested for Anti-NMDA receptor antibodies which were positive. She was
diagnosed as having Anti-NMDA Receptor Encephalitis and started on immediate Plasma Exchange with drastic improvement.
