Extradural haematoma (EDH) with contracoup injury

  • A lens-shaped collection of dense (acute) blood is the classic appearance of an extradural haematoma (EDH)
  • EDH formation commonly results from injury to the middle meningeal artery
  • Post-traumatic intracranial haemorrhage at the site of impact can be referred to as a 'coup' injury
  • A coup injury may be accompanied by a 'contracoup' injury - located on the opposite side of the brain from the site of impact
  • Contracoup injuries are caused by acceleration-deceleration forces at the time of injury

Clinical information

  • Fall from height with direct trauma to the left side of the head
