Post-vaccinal acute disseminated encephalomyelitis: a case report

Abstract

Acute disseminated encephalomyelitis (ADEM) may occur following viral exanthemata or following vaccination. The disorder represents an allergic phenomenon which appears to result from delayed hypersensitivity to myelin basic proteins. On the other hand, circulating immune complexes are postulated to cause vascular injury. In this study we report computerized tomography (CT) findings in a case of ADEM due to Semple type vaccination.
