title: Descending suppurative mediastinitis: nonsurgical approach to this unusual complication of retropharyngeal abscesses in childhood.
abstract: OBJECTIVE
  To alert the pediatric emergency physician about suppurative mediastinitis as an unusual, life-threatening complication of retropharyngeal abscesses in children and to report an alternative therapeutic option for these cases.
  
  
  METHODS
  We describe a case of suppurative mediastinitis secondary to a retropharyngeal abscess in a 19-month-old girl and discuss the pathophysiology, diagnosis, and treatment of this disease.
  
  
  RESULTS
  Prompt diagnosis, based on clinical, radiographic, and CT findings, followed by immediate retropharyngeal drainage and appropriate antibiotic therapy, allowed conservative management of the mediastinal abscess, without the need for surgery. The child presented a good outcome and was discharged on hospital day 14.
  
  
  CONCLUSIONS
  When evaluating a retropharyngeal abscess, the pediatric emergency physician should be aware of its complications. A chest radiograph should be prescribed for each patient presenting with an indolent course. Widening of the mediastinum should be considered as strong evidence of a mediastinal abscess for which the best therapeutic option is aggressive surgical drainage. In the rare cases in which marked improvement is achieved after retropharyngeal drainage, a nonsurgical approach to the mediastinal abscess could be attempted. CT scan and a simple chest radiograph have proved to be useful for diagnosis and follow-up.
