Abstract
Acute disseminated encephalomyelitis (ADEM) is an inflammatory immune-mediated disorder which is more common in pediatric patients. The clinical setting is characterized by a rapid onset of encephalopathy and multifocal neurological features. Acute hemorrhagic encephalomyelitis (AHEM) is considered a rare form of ADEM. This report shows a 2-year-old patient who presented with the classical features of ADEM and after 8 weeks developed severe neurological worsening. The second magnetic resonance image (MRI) showed hemorrhagic lesions. Differences in prognosis between ADEM and AHEM justify the investigation of AHEM whenever a patient has neurological recrudescence in a known patient of ADEM.
