title: "Head to Head": pneumocephalus as a complication of soccer.
abstract: BACKGROUND
  Pneumocephalus is uncommon in craniofacial trauma and a rare occurrence in non-contact sports. It may be asymptomatic or present with signs of increased intracranial pressure and the majority of cases will resolve with conservative management. However, there should be a high index of clinical suspicion to recognise, diagnose, and manage it appropriately, as complications may be fatal.
  
  
  RESULTS
  To our knowledge, this is the first case report of pneumocephalus secondary to a "minor" head injury during a soccer match.
  
  
  CONCLUSIONS
  We outline the management of this condition and highlight signs that should generate a high index of suspicion.
