Epidural intracranial hematoma
The classic presentation involves a brief post-traumatic loss of consciousness, then several minutes to hours of a lucid interval, followed by obtundation and focal neurologic deficits. While this classic clinical description is widely taught, it is seen in < 20% of cases. Other less specific signs and symptoms include headache, nausea and emesis, seizures, neurologic deficits (contralateral weakness, hyperreflexia), papilledema, pupil-involving third-nerve palsy, somnolence, or coma.

428268007 – Extradural intracranial hematoma
- Subdural hematoma
- Diffuse axonal injury
- Intracerebral hemorrhage
- Subarachnoid hemorrhage
- Postictal state
- Metabolic, infectious, or pharmacologic etiology for altered mental status
- Kernohan notch phenomenon (contralateral cerebral peduncle compressed against tentorial notch) may lead to falsely localizing, ipsilateral neurologic deficits.
- Do not fail to recognize other radiographically visible intracranial injuries, including contrecoup intracranial injuries.
- It is important to evaluate for additional traumatic injuries, especially cervical spine injury.
