Epidural Hematoma

Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. Often there is loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of consciousness again. Other symptoms may include headache, confusion, vomiting, and an inability to move parts of the body. Complications may include seizures. The cause is typically head injury that results in a break of the temporal bone and bleeding from the middle meningeal artery. Occasionally it can occur as a result of a bleeding disorder or blood vessel malformation. Diagnosis is typically by a CT scan or MRI. When this condition occurs in the spine it is known as a spinal epidural hematoma. Treatment is generally by urgent surgery in the form of a craniotomy or burr hole. Without treatment, death typically results. The condition occurs in one to four percent of head injuries. Typically it occurs in young adults. Males are more often affected than females.
