Abstract
Bilateral epidural hematomas are very rare and are associated with high mortality. The purpose of this study is to identify the clinical features, mechanisms, and outcomes of bilateral epidural hematomas. This report considers 19 cases of bilateral epidural hematoma hospitalized between 1987 and 1997. All of the cases, with the exception of three, were diagnosed within the first 6 h. The neurologic evaluations on admission and during hospital stay were based on the Glasgow Coma Scale. Hematomas were determined by CT scans in all cases. The patients were evaluated using the Glasgow Outcome Scale after 6 months. In 13 patients, the bilateral epidural hematoma was in the midline. In six patients, hematomas were at different locations on either side. Surgical approach was chosen as the primary treatment modality in 18 patients. One was treated conservatively. The mortality rate was 15.7% in this series. With the widespread use of CT scan, diagnosis before deterioration of the neurological status affects the results of surgery and prognosis or even presents the possibility of a conservative treatment.
