CTICasesBiPAP-Induced Pneumopericardium and Pneumomediastinum
Imaging findings
CT chest in a non-intubated COVID-19 patient receiving non-invasive positive pressure ventilation (BiPAP) shows extensive pneumomediastinum and pneumopericardium without evidence of esophageal rupture.
Key takeaways
Barotrauma (alveolar rupture leading to the Macklin effect) is well-known in mechanical ventilation but can also occur with non-invasive ventilation (BiPAP/CPAP). The positive pressure can dissect air into the mediastinum and pericardial space, especially in diseased lungs with reduced compliance.
