Hematome extra dural pdf
Often there is loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of consciousness again. Spontaneous spinal epidural hematoma (EDH) is a rare condition requiring urgent diagnosis (1−4).Patients with spontaneous spinal EDH typically present with acute onset of severe back pain and rapidly develop signs of compression of the spinal cord or cauda equina .Spinal EDH occurring spontaneously or after minimal trauma has been attributed most often to a venous source (5−7). Typically lentiform (lens-shaped, biconvex, lemon-shaped) and do not cross sutures as the periosteum crosses through the suture continuous with the outer periosteal layer. The most important findings were rapidly developing papilloedema, an ipsilateral hemiplegia, and the angiographic evidence of a pronounced hydrocephalus. Extradural hematoma (EDH), also known as an epidural hematoma, is a collection of blood that forms between the inner surface of the skull and outer layer of the dura, which is called the endosteal layer.They are usually associated with a history of head trauma and frequently associated skull fracture. The source of bleeding is usually arterial, most commonly from a torn middle meningeal artery. Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. Almost always venous due to tearing of subdural cortical bridging veins which extend to the dural sinuses.
Other symptoms may include headache, confusion, vomiting, and an inability to move parts of the body. A subdural haematoma is a serious condition where blood collects between the skull and the surface of the brain.

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.
