Résumé
Acute disseminated encephalomyelitis (ADEM) is an acute inflammatory demyelinating disease of central nervous system, and is related to allergic or immune-mediated reaction to systemic viral infection or vaccination, which is usually self limited monophasic illness. As the clinical manifestations or laboratory findings is nonspecific, it is diagnosed by brain magnetic resonance imaging (MRI) showing multiple foci of increased T2 signal within white matter. We report the clinical and radiologic imaging findings in a 36-year-old man in whom acute disseminated encephalomyelitis developed after serologically proven herpes infection combined with liver abscess. His clinical course, despite without corticosteroid or plasmapheresis because of liver abscess, was shown spontaneous remission.
