Traction bronchiectasis

Traction bronchiectasis refers to an aetiological sub type of bronchiectasis where there is irreversible dilatation of bronchi and bronchioles within areas of pulmonary fibrosis or distorted lung parenchymal architecture.

Pathology

It can arise from a number of underlying causes which result in lung fibrosis. The bronchus is pulled apart by the traction of surrounding parenchymal fibrosis. 

Distribution

There may be a predilection for the upper lobes where there is less supporting cartilage 1.
