A 51-year-old healthy male presented a sudden episode, witnessed by his wife, of diffuse jerky movements during sleep which ceased in a few minutes, rendering the patient confuse, with amnesia of the episode, and evidence of tongue biting. Transferred to the Emergency Department, he had 3 additional, convulsive episodes that were treated with benzodiazepines. He had sustained fever for 3 days prior to admission. A nasopharyngeal swab test using isothermal nucleic acid amplification technology (Alere  i Influenza A & B) confirmed influenza A infection. This episode coincided with an inflenza outbreak. General and neurological examinations were normal. Complete blood counts and blood chemistries were within the normal range. He had no history of prior seizures, febrile seizures, head trauma, stroke, or family history of seizures.
EEG, CSF and neuroimaging findings are described on Table 1. He was discharged on therapy with phenytoin and levetiracetam, both withdrawn after one month. He became afebrile in a week and seizures have not recurred in 18 months.
