ABSTRACT
Neurological complications of Epstein Barr virus (EBV) infection are infrequent and may include occasionally encephalitis, usually with a benign evolution. We here report on an aggressive case of EBV encephalitis in a 14-year-old boy with extensive basal ganglia involvement, and to a lesser degree of brain cortex who presented atypically with akinetic mutism and non-convulsive status epilepticus, requiring intensive care but showed a favorable outcome. EBV encephalitis is uncommon and its best management is unclear. Its pathophysiology is not well understood but could include autoimmunity. Onconeuronal and synaptic antibodies were negative in serum and cerebrospinal fluid, including the dopamine D2 receptor. To the best of our knowledge, this is the first report to evaluate antibodies to D2 receptors in EBV encephalitis. Corticosteroid therapy is usually recommended but the use of acyclovir is controversial. Intensive care is required in severe cases to assure a favorable outcome.
