Subdural hematoma (SDH) and epidural hematoma (EDH) are characterized by bleeding into the spaces surrounding the brain or spinal cord.

Subdural hematomas form between the dura and the arachnoid membranes

Epidural hematomas arise in the potential space between the dura and the skull

Clinical issues related to EDH in adults will be reviewed here. EDH in children and subdural hematoma are discussed separately. (See "Intracranial epidural hematoma in children: Epidemiology, anatomy and pathophysiology" and "Intracranial epidural hematoma in children: Clinical features, diagnosis, and management" and "Subdural hematoma in adults: Etiology, clinical features, and diagnosis".)


EDH is an uncommon, but serious complication of head injury. While the exact incidence is unknown, it is found in 1 to 4 percent of traumatic head injury cases, and 5 to 15 percent of autopsy series [1,2].
