ABSTRACT

Acute disseminated encephalomyelitis (ADEM) is characterized by its clinical signs suggestive of multiple central and peripheral nervous system disorders.
The majority of the authors base their clinicopathological diagnosis on the presence of myelonclastic lesions and has been observed a close relation with a viral infection (Chicken pox, measles, rubella, etc.) it could also be a secondary reaction to the application of vaccine. In some cases it is impossible to identify the causal factor so it is diagnosed as idiopathic or spontaneous case. We received four patients with antecedents of chicken pox, with the apparition of acute neurological symptoms: intracranial hypertension, cerebellar syndrome, meningeal irritation and pyramidal signs. The imagenology studies showed cerebral edema and myelinoclastic areas.
All patients started recovering during the second week of being at the hospital, recovering ad integrum two patients and the rest with moderate sequelae. All of them continue their control in the external neurology consultation and lead a normal life. In all cases we established a close association with varicela as an etiologic factor of a neurological case.
