CTICasesBronchial Anastomotic Dehiscence with Pneumopericardium
Imaging findings
CT chest in a lung transplant recipient two months post-transplant shows a large defect at the right bronchial anastomosis with adjacent necrotic tissue and debris. There is a large pneumopericardium without significant pneumomediastinum.
Key takeaways
Bronchial anastomotic dehiscence is a serious complication of lung transplantation, often secondary to ischemia of the donor bronchus. Air can dissect from the dehisced airway directly into the pericardial space (pneumopericardium) due to surgical disruption of the normal anatomical boundaries between the pericardium and mediastinum.
