Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...

However, some patients have worsening symptoms and imaging findings, with further increase in septal thickening, GGOs, and consolidation.
High magnification photomicrograph of a lung biopsy taken showing chronic hypersensitivity pneumonitis , showing mild thickening of the walls of the small air sacs by invasion of white blood cells. A multinucleated giant cell , seen within the walls of the air sacs to the right of the picture halfway down, is an important clue to the correct ...

It also includes lung manifestations of autoimmune diseases such as Sjögren syndrome or rheumatoid arthritis. [ 3 ] [ 4 ] Histopathologic studies have shown that the tree-in-bud pattern is caused by demarcation of the normally invisible branching course of the peripheral airways, which usually results from bronchioles being plugged or blocked ...
Airway inflammation is increased during the exacerbation resulting in increased hyperinflation, reduced expiratory air flow and decreased gas exchange. [1] [2] Exacerbations can be classified as mild, moderate, and severe. [3] As COPD progresses, exacerbations tend to become more frequent, the average being about three episodes per year. [4]
