Decompressive craniectomy in the acute fulminant cerebral edema

Abstract

Acute fulminant cerebral edema is a type of rapidly progressive encephalitis that occurs in children and is associated with significant morbidity and mortality.

We present a clinical case with seizures, rapid neurological deterioration and the early appearance of cerebral herniation signs. Although the radiological tests were initially normal and there are no established parameters that predict the evolution of encephalitis to a rapidly progressive subtype, the clinical evolution forced to consider the decompressive craniectomy due to the lack of response to the medical management of the cerebral edema. It may be necessary take a brain biopsy to confirm the etiology of the encephalitis origin of acute fulminant cerebral edema. The objective of surgery should be not only to increase survival, but also to reduce subsequent neurological sequelae.
