Fig. 4. 19-year-old female patient with primary ciliary dyskinesia syndrome and concurrent infection with Mycobacterium gordonae.

A. Lung window image of thin-section (2.5-mm-section thickness) CT obtained at level of lower esophagus shows extensive areas of bronchiectasis (arrows) and mucus plugging (arrowheads) in both lungs. Also note patchy areas (open arrows) of mosaic attenuation. B. Coronal reformatted (2.0-mm-section thickness) CT image demonstrates bronchiectasis (arrows) predominantly in lower lung zones. Also note mucus plugging (arrowhead) and parenchymal consolidation (thin arrows).
