A 12-year-old girl with cystic fibrosis. a On the AP radiograph moderate cystic fibrosis changes are seen; the most severe are in the right lower quadrant. b, c Two tomosynthesis sections clearly show cystic bronchiectasis anteriorly in the right hilar region (circle) and varicose bronchiectasis in the perihilar regions bilaterally (white arrows). In addition a small fluid level is seen (black arrow) on the right side. Bronchial wall thickening, multiple cylindrical bronchiectases and small mucus plugs in the periphery are also seen in both lungs. d A section from HRCT of the lungs performed 1.5 months earlier shows bronchiectases anteriorly in the middle lobe and the lingula segment (arrows), and also in both lower lobes. In addition mucus plugging is seen in the right lower lobe (arrowheads)
