Spontaneous retropharyngeal emphysema--case report.
Retropharyngeal emphysema is a radiological finding with a cause for concern. When associated with oesophageal perforation due to an impacted foreign body or recent oesophageal instrumentation, it heralds potentially fatal complications such as mediastinitis. Early diagnosis leading to prompt surgical intervention is essential. Spontaneous retropharyngeal emphysema is an uncommon disease entity. Its clinical course is relatively benign and recovery usually uneventful. Two cases are presented. The anatomy etiology and pathophysiology of the disease are reviewed. Barium swallow studies are recommended for all cases of retropharyngeal emphysema to exclude oesophageal perforation due to foreign body impaction and Boerhaave's syndrome.
