Abstract
Suppurative mediastinitis following neck infection is an uncommon entity that carries a 40% mortality. It is most commonly associated with esophageal perforation or odontogenic abscess. The rapidity of spread has been attributed to dependent drainage from the neck into the mediastinum, negative intrathoracic pressure, and synergistic necrotizing bacterial growth. Cultures obtained usually grow streptococci and/or Bacteroides.
We report the case of a 34-year-old woman with an upper respiratory infection who subsequently was found to have a para-/retropharyngeal and mediastinal abscess. Septic shock, respiratory failure, and death ensued, despite aggressive treatment with broad-spectrum antibiotics (for both aerobes and anaerobes), surgical drainage of the neck and mediastinum, and cardiorespiratory support.
The danger of a rapid downhill clinical course with mortality due to suppurative mediastinitis makes early diagnosis of critical importance. All clinicians evaluating a “sore throat” should consider neck edema or gas on neck radiograms as evidence of cervical abscess, and subsequent widening of the mediastinum on chest x-ray as an ominous sign suggesting mediastinal abscess.
