Study Notes
Types of Head Trauma
-
Coup-Contrecoup Injury
- Typically linked to frontal and temporal lobe damage.
- Involves initial impact (coup) and rebound injury (contrecoup).
-
Concussion
- Causes transient alteration of consciousness.
- Does not necessarily involve structural damage; affects neuronal function temporarily.
-
Diffuse Axonal Injury (DAI)
- Can vary from mild confusion to deep coma.
- Generally results from acceleration or deceleration forces along with shearing injuries.
Extradural Hematoma
- Located between the dura mater and the skull.
- Source of bleeding often comes from torn arteries, typically following skull fractures.
CT Findings
- Important finding includes evidence of cerebral ischemia or infection.
- May present as areas of abnormal density or enhancement on CT scans, indicating underlying injury.
