Background
- Air in the pericardium
- Generally secondary to connection between pericardium and pleural cavity, bronchi, or GI tract
- Most often found following trauma, severe asthma exacerbation, strangulation, or forceful drug insufflation
Clinical Features
- May present with tamponade physiology depending on size
- Other features include:
- Dyspnea
- Cyanosis
- Chest pain
- Pulsus paradoxus
- Bradycardia
- Tachycardia
Differential Diagnosis
Causes of pneumopericardium
- GI malignancy

- SCUBA diving/rapid ascent
- Drug insufflation (especially associated with crack cocaine)
- Asthma
- Valsalva
- Infection pericarditis with gas-producing bacteria
- Thoracic surgery
- Pericardial fluid drainage
- Blast injury
- Blunt or penetrating Thoracic trauma
- Neonatal respiratory distress syndrome
