Figure 7a. Bronchial stenosis in a patient with bilateral lung transplants for pulmonary fibrosis due to systemic sclerosis. (a) Axial chest CT image, obtained more than 12 weeks after transplantation, shows stenosis of the bronchus intermedius (arrow). Esophageal food residue from dilatation caused by scleroderma also is visible. (b) Axial chest CT image, obtained after balloon dilation of the intermediate bronchus, shows mild residual stenosis (arrow).
