title: Spontaneous tracheal rupture caused by vomiting.
abstract: OBJECTIVE
  To present a pediatric case of spontaneous tracheal rupture caused solely by vomiting and to discuss its diagnosis and management.
  
  
  METHODS
  Case presentation and literature review.
  
  
  RESULTS
  A 14-year-old girl with a new diagnosis of type 1 diabetes mellitus presented with respiratory distress. History was significant only for 4 days of violent vomiting, and she was diagnosed with diabetic ketoacidosis. Examination revealed tachypnea and considerable subcutaneous air overlying the upper chest and neck; chest x-ray showed pneumomediastinum. A swallow study showed no evidence of an esophageal tear. Computed tomography of the chest showed a posterior tracheal tear 4.5 cm distal to the cricoid cartilage. The patient's ketoacidosis was controlled, and supplemental oxygen was administered temporarily to promote absorption of the extravasated air. Serial chest x-rays showed complete resolution within 5 days and intubation was not required.
  
  
  CONCLUSIONS
  To our knowledge, this is the first reported pediatric case of tracheal rupture secondary to vomiting. Previous reports of spontaneous tracheal rupture have been related to paroxysmal coughing. In similar cases of subcutaneous emphysema and pneumomediastinum after retching, an esophageal rupture should be ruled out. Conservative management was successful in this case.
