Skull Fracture Types

Approach to the DDX of different types of skull fractures:

  • Linear fracture appears as a thin lucency
  • Diastatic fracture appears as a wide lucency
  • Depressed fracture has fragments that enter the cranium
  • Ping pong fracture can be seen at birth
  • Growing fracture enlarges over time
  • Accessory suture can mimic a fracture and is most confidently diagnosed when there is no associated soft tissue swelling
  • Healing fracture has no periosteal reaction and slowly disappears
