Extradural Hemorrhage

Extradural Hemorrhage Symptoms & Signs

The health care provider should be consulted for any head injury that results in even a brief loss of consciousness or if other symptoms are present after head injury (even without loss of consciousness).

The typical symptom pattern of loss of consciousness, followed by alertness, then loss of consciousness again may not appear in all people, but is highly indicative of an extradural hemorrhage.

The most important symptoms of extradural hemorrhage are:

• Headache, severe
• Drowsiness
• Confusion
• Nausea or vomiting may accompany the headache
• Dizziness
• Enlarged pupil in one eye
• Weakness of part of the body, usually on the opposite side from the side with the enlarged pupil
• Head injury or trauma followed by loss of consciousness, an alert period of time, then rapid deterioration back to unconsciousness
