Axial (a) and coronal (b) reformats of the chest CT following a contrast injection, showing a subcarinal and right hilar ill-defined soft tissue mass (white arrows) with prominent interior calcifications causing marked compression on the bronchus intermedius, right middle lobe bronchus (white arrowhead), and right inferior pulmonary vein (black arrowhead).

These calcifications severely compressed the right bronchial tree, right pulmonary artery, and right inferior pulmonary vein (RPA and RPV), causing complete atelectasis of the RML (Figure 2).
3D reconstruction of the cardiac MRI demonstrates marked narrowing of the right pulmonary artery (black arrowhead) and the right inferior pulmonary veins (white arrowhead).
