CTICasesRadiographic signs of pneumomediastinum
Imaging findings
CT and radiographs show pneumomediastinum characterized by the continuous diaphragm sign (air tracking inferior to the heart) and the ring-around-the-artery sign (air outlining the pulmonary artery).
Key takeaways
Understanding key radiographic signs of pneumomediastinum (such as the continuous diaphragm and ring-around-the-artery signs) is crucial to differentiate mediastinal air from pneumopericardium or pneumothorax.
