Abstract
Fourteen cases of an extradural hematoma of the posterior fossa (EDHPF), are presented and the clinical and radiological findings are described. The onset of symptoms was acute in 10 patients and subacute in the other 4. Hematomas occurred in the younger age groups with a clear male predominance. Nine cases had suffered a blow to the head. A fracture of the occipital bone was seen in 86% of the patients. The bleeder could be identified in 10 cases, and in 6 of these the source was a bleeding transverse sinus. The overall mortality was 14.2%, but only patients with an acute course died (20%). All subacute cases survived. This study revealed that the most important factors influencing mortality were late diagnosis and late treatment. Coexisting intracranial lesions had no influence on mortality. According to the literature, there has been a certain decrease in mortality in the acute and subacute course patients since the introduction of computed tomography (CT) scanning. Emphasis is placed on the importance of occipital soft-tissue swelling and occipital fracture as clues to the possible presence of extradural hematomas, and of using the CT in all such patients even if no clinical symptoms are present.
