They are spiral-shaped mucus plugs from subepithelial mucous gland ducts of bronchi. They may occur in several different lung diseases [1] and may refer to parts of the desquamated epithelium seen in lavages from asthmatic patients. [2] These microscopic casts are named after German physician Heinrich Curschmann (1846-1910).
Allergic bronchopulmonary aspergillosis; Other names: ABPA, Hinson-Pepys disease. The chest radiograph of an allergic bronchopulmonary aspergillosis patient shown with left-sided perihilar opacity (blue arrow) along with non-homogeneous infiltrates (transient pulmonary infiltrates indicated by red arrows) in all zones of both lung fields.
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 ...
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
The light-colored plugs take the branching shape of the bronchi that they fill, and are known as bronchial casts. [81] When these casts are coughed up, they are firmer in texture from typical phlegm or the short, softer mucus plugs seen in some people with asthma. [81] However, some people with asthma have larger, firmer, and more complex plugs.
Sputum is mucus that is coughed up from the lower airways (the trachea and bronchi).In medicine, sputum samples are usually used for a naked eye examination, microbiological investigation of respiratory infections and cytological investigations of respiratory systems.
Fungal tracheobronchitis can be invasive into the lung tissue or pulmonary artery and cause a severe lung infection. The extra secreted mucus from tracheobronchitis plugs the airways allowing the fungal pathogens to lodge and multiply. Local damage to the tracheal wall that can be caused by mechanical ventilation is a risk factor for this.
The development of bronchiectasis requires two factors: an initial injury to the lung (such as from infection, auto-immune destruction of lung tissue, or other destruction of lung tissue (as seen in gastroesophageal reflux disease or aspiration syndromes)) which leads to impaired mucociliary clearance, obstruction, or a defect in host defense.
