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 ...
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 ...
[11] [18] This is sometimes accompanied by the development of a crazy paving pattern and interlobular septal thickening. [18] In many cases the most severe pulmonary CT abnormalities occurred within 2 weeks after symptoms began. [17] At this point, many individuals begin showing resolution of consolidation and GGOs as symptoms improve.
Mild peribronchial cuffing as seen in viral bronchitis. A physical examination will often reveal decreased intensity of breath sounds, wheezing, rhonchi, and prolonged expiration. During examination, physicians rely on history and the presence of persistent or acute onset of cough, followed by a URTI with no traces of pneumonia.
Bronchiolitis obliterans (BO), also known as obliterative bronchiolitis, constrictive bronchiolitis and popcorn lung, is a disease that results in obstruction of the smallest airways of the lungs (bronchioles) due to inflammation. [1] [6] Symptoms include a dry cough, shortness of breath, wheezing and feeling tired. [1]
When associated with disease, it is known as "Respiratory bronchiolitis-associated interstitial lung disease" or "RB-ILD". [4] Also, this disease is predominantly found in the upper lobe with centrilobar ground glass nodules. Importantly, no fibrosis is involved, just bronchial wall thickening. Treatment is to stop smoking.
CT scan in a patient with usual interstitial pneumonia, showing interstitial thickening, architectural distortion, honeycombing and bronchiectasis.. In radiology, honeycombing or "honeycomb lung" is the radiological appearance seen with widespread pulmonary fibrosis [1] and is defined by the presence of small cystic spaces with irregularly thickened walls composed of fibrous tissue.
These include the features of chronic bronchitis such as inflammation of the small airways and mucus production or hypersecretion. [1] Peribronchial inflammation may lead to fibrosis (obliterative bronchiolitis) [1] as well as features of emphysema, including inflammation leading to alveolar destruction resulting in lung hyperinflation and air ...
