An extradural hematoma (EDH) (also known as an epidural hematoma) is a collection of blood which forms between the inner surface of the skull and outer layer of the dura.

Epidural or extradural hematoma is a type of traumatic brain injury.

An epidural hematoma usually presented early in the acute phase, but here in our case is presented as an aging hematoma in the late subacute phase.
