Epidural bleeding occurs between the skull and dura; whereas subdural bleeding occurs between the dura and arachnoid.
Skull fracture from blunt trauma causes laceration of arterial vesselsmost commonly the middle meningeal artery. Fracture occurs most commonly in the region of the temporal bone.
In contrast to subdural hematomas, a tremendous force is usually required. In children, in whom the skull is more deformable, temporary displacement of skull bones may lead to laceration of a vessel without fracturing the skull.

This is then followed by headache, progressive obtundation, and hemiparesis. An epidural hematoma is a neurosurgical emergency! Since bleeding is under artertial pressure, the hematoma may expand rapidly. Prompt drainage is almost always necessary.

Mortality is largely due to increased intra-cranial pressure and herniation. Head trauma causes rupture of the bridging veins. The bridging veins are susceptible to rupture because the brain floats freely in CSF whereas the venous sinuses are fixed. Displacement of the brain can cause tearing at the point where the bridging veins penetrate the dura.
The elderly and alcoholics with brain atrophy are particularly susceptible since the bridging veins are stretched out and the brain has more space for movement. Hence a subdural hematoma may occur with minor head trauma or, in some instances even hemorragoa.
There extradjral be focal signs but clinical signs are most often non-localizing and include headache and altered mental status. Focal signs, if present, may include contralateral hemiparesis.
In contrast to epidural hematoma, changes may be subacute or even chronic. In the elderly the change in mental status may be so gradual that they can present as dementia but a careful history will reveal a remote fall.
Crescent-shaped, concave hyperdensity that does not cross the midline. Midline shift and compression of lateral ventricle may also be present.
Acute subdural hematoma is a neurosurgical emergency! The high morbidity and mortality is due to parenchymal damage underlying the hematoma and raised intracranial pressure.
