title: Post-Traumatic Bifrontoparietal Extradural Hematoma with Superior Sagittal Sinus Detachment: A Case Report and Review of the Literature.
abstract: OBJECTIVE
  To present, to our knowledge, the first case of a single bilateral extradural hematoma due to superior sagittal sinus detachment that was treated conservatively with an excellent outcome.
  
  
  METHODS
  Bilateral extradural hematomas are a rare condition, accounting for only 2%-5% of all extradural hematomas. They can be either 2 distinct hematomas on either side or 1 single bilateral hematoma mostly due to sagittal sinus injury, with the latter being the most rare owing to the firm attachment of the sinus to its subperiosteal loggia. These hematomas usually require immediate surgical evacuation, as patients present with decreased level of consciousness, and have good postoperative outcomes. We present a bilateral extradural hematoma due to superior sagittal sinus injury, which was treated conservatively.
  
  
  RESULTS
  The patient had an excellent recovery, with no residual neurological deficits and a Glasgow outcome scale of 5 on discharge.
  
  
  CONCLUSIONS
  Bilateral extradural hematomas due to superior sagittal sinus injury almost always require surgical intervention. We present a patient who was treated conservatively with an excellent outcome and we also perform a review of the current literature.
