Chest computed tomography findings. The upper row is the axial plane (lung window). The middle row is the axial plane (mediastinal window). The lower row is the three-dimensional reconstruction of the tracheal tree. (a) At 3 months (before onset). Both lungs are equally ventilated. Bronchial stenosis is not seen. (b) At 8 months (at onset). The left lung is collapsed because of the atelectasis. The left bronchus is shifted toward the left posterior. The left bronchial stenosis is due to compression by the descending aorta (arrows). (c) At 8 months (after treatment). Atelectasis in the left lung is corrected; the left bronchial stenosis is ameliorated (arrows). (d) At 11 months (before discharge). The left bronchial stenosis has been successfully managed, while the patient's condition has shown further improvement (arrows).

At 8 months of age, chest computed tomography showed a left bronchial shift toward the left posterior and a left bronchial stenosis because of compression by the descending aorta and massive atelectasis in the left lower lobe (Figure 1). Two weeks after initiating treatment, chest computed tomography and bronchofiberscopy showed amelioration of the left bronchial stenosis and atelectasis (Figure 1).
Bronchofiberscopy findings: (a) At 8 months (at onset). Severe left bronchial stenosis and pulsation of the posterior bronchial wall that might be caused by the descending aorta are shown. (b) At 11 months (before discharge). Amelioration of the left bronchial stenosis is shown.

Bronchofiberscopy showed severe left bronchial stenosis and a pulsation of the posterior bronchial wall, possibly due to the descending aorta (Figure 2).
