Evolution from viral encephalitis to autoimmune encephalitis to multiple sclerosis: a case report.

This unique case report links three important neuroimmunological entities in characterizing the evolution from infectious to autoimmune encephalitis to multiple sclerosis in one patient. Identification of such rare clinical constellations is critical for correct treatment choice and provides important novel insights into the pathophysiology of neuroimmunological disorders including viral triggers and overlap manifestations of autoimmune CNS diseases.
