[Extradural hematoma of the posterior fossa]

Extradural hematoma of the posterior fossa (EDHPF) is considered to be a rare complication of head injuries. In early reports, diagnosis was made only at the time of autopsy. Today, CT scanning prompts early diagnosis leading to better outcome. We report 20 consecutive patients observed over the last ten years who underwent surgery for EDHPF. This localization was found in 14,3% of all trauma patients operated for extradural hematoma. In our experience, EDHPF occurs in young adults with a clear male predominance. Vehicle accidents are the most frequent mechanism of injury. The main clinical presentation is subacute onset of signs (50% of our cases). Postoperative outcome was favorable in 19 of our patients (95%). We propose mandatory CT scanning that may have to be repeated as needed, to prevent delay in diagnosis and decision for surgery. Surgical removal of the EDHPF must be carried out as soon as possible as this is the only way to reduce morbidity and mortality.
