Traumatic epidural haematomas of the posterior fossa: 20 new cases and a review of the literature since 1961.
Twenty patients with an epidural haematoma of the posterior fossa (EPIPF) among a total number of 359 patients with an epidural haematoma are reported (5.6%). Nine patients obtained a good outcome, four patients had a moderate disability and seven patients died (mortality 35%). Mortality of the acute cases was 50%, of the subacute cases 20%. In general, the clinical features were uncertain. Sixteen cases showed an occipital skull fracture or diastasis of the lambdoid suture respectively. A total number of 127 cases with EPIPF from the literature since 1961 was studied. The mortality in the CT-diagnosed group ran to 21.7% and to 25.9% in the group without CT. None of the patients showing a subacute course died when the diagnosis was made by CT, in the group without CT, however, four patients out of 11 subacute cases died. Head injured patients with an occipital trauma should therefore undergo CT scanning to detect a surgically significant lesion before clinical deterioration occurs.
