The interior of the skull has sharp ridges by which a moving brain can be injured. The most common cause of intracranial<unk>  is head injury, although spontaneous hemorrhages have been known to occur.<unk> s occur in about 10% of traumatic brain injuries, mostly due to car accidents, assaults, or falls. They are often caused by acceleration-deceleration trauma and transverse forces.<unk>  commonly results from a blow to the side (temporal bone) of the head. The pterion region, which overlies the middle meningeal artery, is relatively weak and prone to injury. Only 20 to 30% of<unk> s occur outside the region of the temporal bone. The brain may be injured by prominences on the inside of the skull as it scrapes past them.<unk>  is usually found on the same side of the brain which was impacted by the blow, but on very rare occasions it can be due to a contrecoup injury. A "heat<unk> " is an<unk>  caused by severe thermal burn, causing contraction and exfoliation of the dura mater and exfoliate from the skull, in turn causing exudation of blood from the venous sinuses. The<unk>  can be seen on autopsy as brick red, or as radiolucent on CT scan, because of heat-induced coagulation of the<unk> .
