Possible mechanisms for rapid spontaneous resolution of acute epidural hematomas

Background: Acute epidural hematomas (EDH), often associated with additional cranial and extracranial injury, are a serious condition which requires immediate surgical evacuation. Otherwise there is a high risk of quick deterioration and death. Only small asymptomatic hematomas can be treated conservatively with close observation. Case Report: We present a case of complete resolution of a traumatic posterior fossa EDH within 1 hour. Conclusion: Several possible mechanisms of spontaneous resorption are discussed with a review of literature regarding the conservative treatment of acute epidural hemorrhage. This is the first description of the spontaneous resolution of an acute traumatic EDH within 1 hour.
