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

Subdural hematomas form between the dura and the arachnoid membranes

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

The pathophysiology, etiology, clinical features, and diagnostic evaluation of SDH will be discussed here. Treatment of SDH is reviewed separately. (See "Subdural hematoma in adults: Prognosis and management".)

Epidural hematoma is discussed elsewhere. (See "Intracranial epidural hematoma in adults".)
