Although epidural hematomas (EDH) are not frequently seen with intracranial injury in trauma, they present an emergency situation that can result in significant mortality if not diagnosed and treated in a timely manner. EDH stems from bleeding from the bone rupturing an interosseous artery, the bone itself, or from a venous sinus laceration. Most EDH present with a classic biconvex shape on CT images. Venous EDH can cross the midline and are often found under the transverse or sagittal sinus. The current school of thought is that patients who present with a small (<10 mm maximal thickness) EDH with no neurological symptoms can be treated conservatively. Patients neurologically intact with a normal Glasgow Coma Scale score but an EDH of greater than 30 cc should undergo surgery.
