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.

Review of the CT scan showed ground-glass opacification, mild subpleural honeycombing, reticularity, and traction bronchiectasis bilaterally at the lung bases.
IPF: The presence of bilateral honeycombing, reticular opacities, traction bronchiectasis, sub pleural cysts with minimal or no ground glass opacities and predominant basal involvementwith exclusion of other causes of ILD.
This UIP pattern in IPF is recapitulated on the macroscopic level and is visible radiographically as peripherally accentuated interstitial fibrosis with lower lobe predominance, traction bronchiectasis, and honeycombing.
A high resolution CT (HRCT) chest was consistent with ground glass opacities in both the lower zones with some degree of traction bronchiectasis (Figure 1).
In our study, we found five radiologic patterns on CT scan; (1)non-specific ground-glass attenuation 17(34%),(2) patchy distribution of ground-glass attenuation accompanied by interlobular septal thickening 7(14%), (3)multifocal areas of airspace consolidation 7(14%),(4)extensive bilateral ground-glass attenuation or airspace consolidations with traction bronchiectasis 4(8%), and (5) nodules of variable sizes randomly distributed in both lungs 15(30%).
Abnormal pulmonary lesion patterns (ground-glass opacity, consolidation, parenchymal bands, air trapping, and reticulation) and evidence of fibrosis (architectural distortion, traction bronchiectasis, or honeycombing) were evaluated on follow-up thin-section CT.
Ground glassing was observed in 24(24%) patients while bronchiectatic changes were evident in another 24(24%) cases with 12 patients showing traction bronchiectasis.
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.
A subpleural reticular pattern associated with focal thickening of the pleura and traction bronchiectasis and bronchiolectasis is also noted.
5) In many cases, however, questions arise as to whether honeycomb lung is actually present or, alternatively, whether the cystic changes seen on the HRCT scan more accurately represent traction bronchiectasis.
The lung abnormalities included nondependent ground-glass or reticular abnormalities, diffuse centrilobular nodularity, nonemphysematous cysts, honeycombing, and traction bronchiectasis.
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.
