traction bronchiectasis

traction bronchiectasis

a phenomenon in which bronchi and bronchioles are pulled open by surrounding pulmonary fibrosis or an increase in elastic recoil. This is seen in association with cicatrization atelectasis.

As with the other disorders discussed above, the HRCT findings of end-stage sarcoidosis can show overlap with IPF, including irregular reticulation, traction bronchiectasis, and honeycombing.

Small branching airways that are adjacent to scars can be diagnosed confidently as traction bronchiectasis, but at what scale does traction bronchiectasis end, and end-stage lung disease begin?
Four patients had radiographic features of usual interstitial pneumonia (UIP) on high-resolution computerized tomographic scan, with bibasilar reticular infiltrates with traction bronchiectasis and subpleural honeycomb change.
Ground glassing was observed in 24(24%) patients while bronchiectatic changes were evident in another 24(24%) cases with 12 patients showing traction bronchiectasis. There were cavities in 16(16%) of which 8(50%) cases had multiple cavities and 4(25%) had single cavity, 2(12.5%) had heterogenous densities within and another 2(12.5%) cases demonstrated the meniscus sign.
Other CT findings were as follows: Air trapping in 9/24 (37.5%) [Figure 2], reticulation in 8/24 (33.3%), and traction bronchiectasis in 2/24 (8.3%).
Higher levels of seven or more ACPAs were significantly more common in patients with reticulation, honeycombing, or traction bronchiectasis than in those with no ILD (40% vs.
Higher number of traction bronchiectasis were detected on HRCT thorax method as compared to chest X-ray but it was not statistically significant (P>0.05).
(5,6) Although radiographic findings, including bibasilar fibrosis, ground-glass opacities, interlobular reticulation, and traction bronchiectasis, have been described, the corresponding histopathology has been poorly documented.
An extended and coarse subpleural reticular pattern is noted associated with traction bronchiectasis and bronchiolectasis as well as with honeycombing.
The lung abnormalities included nondependent ground-glass or reticular abnormalities, diffuse centrilobular nodularity, nonemphysematous cysts, honeycombing, and traction bronchiectasis. Interstitial lung abnormalities were associated with both a decrease in total lung capacity and a lesser amount of emphysema.
