CASE REPORT: The case presented here is a right pericardial laceration with tension pneumopericardium due to falling from a height, presenting to the emergency clinic of our hospital with hemodynamic instability. CONCLUSION: Pneumopericardium that might develop due to blunt thoracic trauma can easily be diagnosed, may result in cardiac tamponade, and is a potentially fatal pathology without treatment.
