A 7-year-old with new-onset seizures, behavior disturbance, and encephalitis.

Refractory seizures are common in pediatric neurology; consideration of whether seizures are acutely symptomatic of an underlying disease process is critical. In this case, a previously healthy 7-year-old patient presented with intractable focal seizures in the setting of a viral prodrome and headache. This case highlights a comprehensive work up of new-onset refractory seizures in a patient with features of encephalitis and describes a diagnostic quandary that ultimately led to a rare unifying diagnosis.
