title: Pneumocephalus after endoscopic odontoidectomy in a pediatric patient: the lesson learned.
abstract: BACKGROUND
  Postoperative pneumocephalus is an unexpected condition after endoscopic odontoidectomy surgery.
  
  
  METHODS
  We present the first case of pneumocephalus after odontoidectomy in a pediatric patient. The clinical presentation, radiological findings, and surgical procedures are described with related pathophysiology.
  
  
  CONCLUSIONS
  We outline the key for management of a rare intracranial air entrapment case after an endoscopic odontoidectomy surgery in a pediatric patient and the measures taken to prevent its occurrence in the future.
