Severe enteroviral encephalitis complicated by encephalomalacia--case presentation.

Enteroviral encephalitis is a rare neuroinfection more often diagnosed in children within the context of enteroviral epidemic outbreaks. It has pleomorphic clinical features, variable severity and a definite potential to cause neuropsychological sequelae especially in infants. Some subtypes are extremely severe with a mortality rate of up to 25% by affecting the brain stem. These subtypes usually come with highly specific findings on neuroimaging. We present a paediatric case of diffuse encephalitis most likely enteroviral in nature, with some particular features concerning the severe clinical form, the neuroimaging aspects and the neuropsychological sequelae due to the rarely described evolution towards encephalomalacia.
