    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.
