Axial view of chest CT shows severe compression of the left main bronchus (LMB) (white arrow) by the esophageal stents. Due to the self-expanding metal stents inserted into the esophagus, LMB was completely obstructed, and subsequential obstructive pneumonia occurred in the left lung. PA, pulmonary artery; RMB, right main bronchus; AAo, ascending aorta; DAo, descending aorta.
