GROSS ANATOMY

Detailed explanation-1: -An epidural hematoma (EDH) is usually caused by a head injury. A skull fracture occurs in 75% of the cases. A skull fracture that tears the middle meningeal artery is the most common source of bleeding. Occasionally, an EDH can form due to bleeding from a vein.

Detailed explanation-2: -Extradural hematoma was most common with parietotemporal linear skull fractures (73.5%). Conclusion: Extradural haematoma occurs commonly with linear skull fractures, so patients with linear skull fracture should be properly evaluated with CT brain.

Detailed explanation-3: -The space between the dura and the skull is called the extradural space. If a blood vessel within this space is injured, blood can leak out and a haematoma (clot) can form. This type of injury is usually associated with a skull fracture and the tearing of an artery which covers the dural layer.

Detailed explanation-4: -Extradural hematoma; Extradural hemorrhage; Epidural hemorrhage; EDH. An epidural hematoma (EDH) is bleeding between the inside of the skull and the outer covering of the brain (called the dura matter).
