Adult Acute Disseminated Encephalomyelitis Associated with a Falsely Positive HIV Elisa Test

Abstract

Acute disseminated encephalomyelitis (ADEM) is an acute disorder of the central nervous system that follows an infection or vaccination. It is a non-vasculitic inflammatory condition resulting in perivascular edema, inflammation, and demyelination that bears resemblance to multiple sclerosis. The diagnosis of ADEM can be challenging since there is a wide set of alternative diagnoses, including opportunistic infections, vasculitis, and central nervous system lymphoma.
