CTICasesPost-Transplant Pneumopericardium
Imaging findings
Lateral chest radiograph shows air outlining the anterior and posterior walls of the ascending aorta. CT chest confirms air collections located in the superior recesses and transverse sinus of the pericardium rather than the mediastinum, arising after a right lung transplant.
Key takeaways
Post-transplant air surrounding the ascending aorta is often due to pneumopericardium within the superior pericardial recesses, rather than pneumomediastinum, resulting from surgically created communications during vascular anastomosis.
