Coronal CT scan and 3D reconstruction of tracheobronchial anatomy. (A) Coronal chest CT demonstrating significant pathological changes. The red arrow indicates a suspected tracheal lesion near the carina. The right lung (R) shows signs of collapse or atelectasis. (B) 3D reconstruction of the tracheobronchial tree highlighting the structural anatomy. The right bronchus (R) is not visualized, suggesting a possible rupture, consistent with the findings on the CT scan
