extradural haemorrhage

epidural hemorrhage

Haemorrhage into the epidural space, which occurs in 10% of patients with severe head trauma; 80% are associated with skull fractures, especially of the temporal bone; many of these disrupt the middle meningeal artery, veins, dural-venous sinuses, and skull vessels.
Clinical findings
Continued bleeding causes intracranial hypertension, uncal herniation and, if untreated, death.

extradural haemorrhage

Bleeding between the skull and the outer layer of brain lining (the dura mater). This usually results from a skull fracture, is often slow and insidious, and is very dangerous. A person who recovers consciousness after a head injury and then lapses once again into coma, probably has an extradural haemorrhage and is likely to be in grave danger.
