Extradural hematoma of the posterior fossa. A series of 20 consecutive cases

Extradural hematoma of the posterior fossa (EDHPF) is considered to be a ra re complication of head injuries. In early reports, diagnosis was made only at the rime of autopsy. Today, CT scanning prompts entry diagnosis lending to better outcome. WE report 20 consecutive patients observed over the las t ten rears who underwent surgery for EDHPF. This localization was found in 14,3 % of air trauma patients operated for extradural hematoma. In our experience, EDHPF occurs in young adults with a clear male predomina nce. Vehicle accidents are the most frequent mechanism of injury. The main clinical presentation is subacute onset of signs (50 % of our eases). Posto perative outcome was favorable in 19 of our patients (95 %). We propose man datory CT scanning that may have to be repeated as needed, to prevent delay in diagnosis anti decision for surgery. Surgical removal of tile EDHPF mus t br carried out as soon as possible as this is tile only M way to reduce m orbidity and mortality.
