Abstract:
Pneumopericardium is a rare but serious finding. It may indicate severe chest trauma and be associated with tracheobronchial and oesophageal injuries. On the other hand, oesophageal rupture such as Boerhaave's syndrome may also be accompanied by pneumopericardium. A case of spontaneous pneumopericardium and pneumomediastinum after alcohol-induced emesis is reported. Tracheal, bronchial, and oesophageal injury were excluded by radiology and endoscopy. Interstitial lung emphysema is discussed as the pathogenesis.
