A 45-year-old male involved in a road traffic accident. a The chest radiograph identified the presence of pneumopericardium most evident adjacent to the right heart border with cardiac displacement. There are multiple injuries but note the gross surgical emphysema that limited the FAST assessment.b On the selected axial CT image on soft tissue window settings, there is extensive surgical emphysema (thin white arrows), pneumopericardium (thick white arrow) and note the displacement of the heart posteriorly into the left hemithorax (black asterisk). This patient had sustained a left-sided pericardial tear with cardiac herniation that was surgically repaired. (a Reprinted with permission from [18])
