title: Hypodensity of extradural hematomas in children: an ominous sign.
abstract: OBJECTIVE
  The aim of this study was to analyze the correlation of hypodensity in extradural hematomas on CT with the clinical profile in pediatric patients. This is the only study available in this age group.
  
  
  METHODS
  This was a prospective study conducted over a period of 3 years in which all children 18 years old or younger with a diagnosis of cranial extradural hematoma were included. The patients were allocated to 2 groups: those with mixed-density clots (17 cases) and those with classically hyperdense clots (52 cases). A comparative analysis between the 2 groups was conducted.
  
  
  RESULTS
  Patients with mixed-density clots presented earlier to the hospital, had poor Glasgow Coma Scale scores at admission, exhibited large clot volumes, had a high incidence of active bleeding at surgery, and had increased morbidity and mortality as compared with the patients with hyperdense extradural hematomas.
  
  
  CONCLUSIONS
  Early recognition and rapid evacuation of the mixed-density clot with restoration of hemostasis may result in a decline in morbidity and death in children with this entity.
