Epidural hematoma

Epidural hematoma: A hematoma between the cranium (skull) and the brain's tissue-like covering, which is known as the dura. Epidural hematoma is usually caused by a full-on blow to the head, and is often associated with a skull fracture. Diagnosis is usually by CAT scan. Treatment is by trepanation: drilling through the skull to drain the excess blood.
