Bronchiectasis

Extensive bilateral bronchiectasis; the massively dilated bronchi extend almost to the pleura. Widespread bronchiectasis is typical for patients with cystic fibrosis who have recurrent infections and obstruction of airways by mucus throughout the lungs.

Cross-section of lung demonstrating dilated bronchi extending almost to the pleura.

Bronchiectasis


A closer view demonstrates the focal area of dilated bronchi with bronchiectasis. Bronchiectasis tends to be localized with disease processes such as neoplasms and aspirated foreign bodies that block a portion of the airways. Note that the dilated bronchi can be traced down to the pleura.
Segmental Bronchiectasis

Segmental distribution of bronchiectasis. The bronchi are dilated into cavities. The dilated bronchi are filled with gelatinous inspissated mucus.

The mid lower portion of this photomicrograph demonstrates a dilated bronchus in which the mucosa and wall is not clearly seen because of the necrotizing inflammation with destruction.
