ABSTRACT

Acute disseminated encephalomyelitis is a rare, acute, inflammatory, and demyelinating disease of the central nervous system. Presumably associated in more than three quarters of cases by infections (viral, bacterial, or nonspecific) and immunizations or without any identifiable antecedent. It usually presents a monophasic course with onset of nonspecific symptoms in the prodromal phase and may evolve with multifocal neurological changes and even visual acuity loss. We describe a case of a 9-year-old boy with an initial picture of papillary edema caused by acute disseminated encephalomyelitis due to Bartonella henselae. Despite the severity of the disease, early diagnosis and treatment provided good outcomes.
