Preferred Label : traction bronchiectasis;
Definition : CT scans.—Traction bronchiectasis and traction bronchiolectasis respectively represent
irregular bronchial and bronchiolar dilatation caused by surrounding retractile pulmonary
fibrosis (130). Dilated airways are usually identifiable as such (Fig 69) but may
be seen as cysts (bronchi) or microcysts (bronchioles in the lung periphery). The
juxtaposition of numerous cystic airways may make the distinction from pure fibrotic
honeycombing difficult. [Fleischner Society];
