Epidural hematoma commonly results from a blow to the side of the head. The pterion region which overlies the middle meningeal artery is relatively weak and prone to injury. 10 Thus only 20 to 30 of epidural hematomas occur outside the region of the temporal bone. 11 The brain may be injured by prominences on the inside of the skull as it scrapes past them. Epidural hematoma is usually found on the same side of the brain that was impacted by the blow, but on very rare occasions it can be due to a contrecoup injury.

12 diagnosis edit On images produced by ct scans and mris, epidural hematomas usually appear convex in shape because their expansion stops at the skull's sutures, where the dura mater is tightly attached to the skull. Thus they expand inward toward the brain rather than along the inside of the skull, as occurs in subdural hematoma. The lens-like shape of the hematoma causes the appearance of these bleeds to be "lentiform". Epidural hematomas may occur in combination with subdural hematomas, or either may occur alone. 10 ct scans reveal subdural or epidural hematomas in 20 of unconscious patients. 13 In the hallmark of epidural hematoma, patients may regain consciousness and appear completely normal during what is called a lucid interval, only to descend suddenly and rapidly into unconsciousness later. The lucid interval, which depends on the extent of the injury, is a key to diagnosing epidural hemorrhage. If the patient is not treated with prompt surgical intervention, death is likely to follow.

Epidural bleeds can become large and raise intracranial entry pressure, causing the brain to shift, lose blood supply, or be crushed against the skull. Larger hematomas cause more damage.

Hemorrhages commonly result from acceleration-deceleration trauma and transverse forces. 7 9 The majority of bleeds originate from meningeal arteries, particularly in the temporal region. 10 of epidural bleeds may be venous, 10 due to shearing injury from rotational forces.
