case_images: His chest digital radiography image showed that a part of the main trachea was seemingly wider than normal (Figure 1).
case_images: CT images of the lung demonstrating an enlarged trachea on the level of 2 cm above the aortic arch. The axial image (down-left) and coronal image (right) showed that the diameter of the trachea was 27.2 mm. The sagittal diameter (up-left) of the trachea was 22.3 mm (A). CT images of the lung on the level of the aortic arch, where the diameter of the trachea was the longest. The transverse diameter on the down-left axial image was 30.5 mm. The diameter on the right coronal image was 30.4 mm. Also, the sagittal image (up-left) demonstrated that the diameter of the trachea was 27.6 mm (B).

case_images: TBM was considered by these standard radiological images (Figures 2, 3).
case_images: Bronchoscopy images showing that the mucosa protrudes between cartilaginous rings in trachea (left) and diverticula in the opening of the middle and lower lobes of the right lung (right).
