Acute disseminated encephalomyelitis (ADEM) is a monophasic central nervous system inflammatory demyelinating disorder clinically defined by multifocal neurologic symptoms with encephalopathy. Brain magnetic resonance imaging most often reveals multiple T2 hyperintense lesions consistent with demyelination. High-dose corticosteroids are the current treatment of choice, and intravenous immunoglobulin or plasmapheresis is considered in steroid-unresponsive cases. The majority of patients show favorable outcomes with full clinical recovery and complete or partial resolution of previous lesions. For patients who are refractory to multiple immunomodulatory agents, other treatments such as rituximab have been used. We present a patient who developed ADEM after Epstein-Barr virus infection who achieved full recovery with immunotherapy including rituximab.
