Abstract:

Bronchiectatic lung cysts are larger on inspiration than on expiration. Bullae do not change in size during the different phases of respiration. By adding expiratory CT scans when cystic lung lesions are found, it is possible to distinguish bronchiectatic cysts from bullae.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
