title: Rapid resolution of acute subdural hematoma in child with severe head injury: a case report.
abstract: BACKGROUND
  Rapid spontaneous resolution of traumatic acute subdural hematoma is an infrequent phenomenon and mainly develops in a case of simple acute subdural hematoma without parenchymal contusion. However, it has been rarely reported in a pediatric case with severe initial head injury.
  
  
  METHODS
  A 7-year-old Asian girl with traumatic acute subdural hematoma was transferred to our hospital for an emergency operation based on the results of an initial computed tomography scan and neurological examination. However, a repeat computed tomography scan two hours after trauma disclosed considerable reduction of the hematoma and midline shift with neurological improvements. Serial follow-up imaging studies demonstrated apparent redistribution of the hematoma over the cerebellar tentorium, posterior interhemispheric fissure and subarachnoid space. The patient was discharged with mild confusion 40 days after the admission.
  
  
  CONCLUSIONS
  A follow-up computed tomography scan is strongly recommended before surgery when a child with a severe head injury presents with any sign of neurological improvement, especially with a mixed density hematoma on the initial computed tomography scan.
