It is well known that the mortality of epidural hematoma (EDH) cases is directly related to the patient's level of consciousness at the time of surgery. The authors report three actually asymptomatic patients with mild head injury, in whom the diagnosis of EDH was possible because of quite broad indications for computed tomographic (CT) scanning, which allowed diagnosis and treatment in an early phase. These cases illustrate the possibility of an EDH in a totally asymptomatic patient.
