title: Intracranial hemorrhage in children younger than 3 years: prediction of intent.
abstract: OBJECTIVE
  To determine whether certain computed tomographic imaging patterns in infants and young children with intracranial hemorrhage help predict intentional compared with unintentional injuries.
  
  
  METHODS
  Retrospective consecutive case series over a 10-year period.
  
  
  METHODS
  Two hundred ninety-three children younger than 3 years with intracranial hemorrhage.
  
  
  METHODS
  The sensitivity and specificity of computed tomographic imaging patterns for intentional head injury.
  
  
  METHODS
  Regional pediatric medical center.
  
  
  RESULTS
  Four variables used in the multiple logistic regression analysis for predicting intentional head injury were statistically significant (P<.05): subdural hematoma located over the cerebral convexities, hematoma within the interhemispheric subdural space, hygroma (nonhemic subdural fluid) with intracranial hemorrhage, and absence of a skull fracture with intracranial hemorrhage. The prediction model for the diagnosis of intentional head trauma using combinations of these 4 variables and a.45 probability cutoff point indicated a sensitivity of 84% (95% confidence interval, 78%-90%) and a specificity of 83% (95% confidence interval, 74%-89%).
  
  
  CONCLUSIONS
  Computed tomographic imaging patterns of intracranial hemorrhage in children younger than 3 years help predict whether the injury was intentional.
