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).
Central (confined to medial two-thirds of the medial half of the lung) bronchiectasis that peripherally tapers bronchi is considered a requirement for ABPA pathophysiology, though in up to 43% of cases, there is a considerable extension to the periphery of the lung. [1] Mucoid impaction of the upper and lower airways is a common finding. [1]
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
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 ...
This particular variant of lung cancer is usually asymptomatic and is found after chest x-rays are taken for other reasons. [7] Hemoptysis is seen occasionally [7] and, in some cases, distal obstruction of bronchi by blood clots or mucus plugs produces cough and/or infection. [1] Lesions often enlarge and progress slowly, over many years. [8]
Along with tea, sipping on clear hot bone broth can also help to moisturize your mucous membranes and promote better mucus flow, says Dr. Mercola. Broths are rich with amino acids, minerals, and ...
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.
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.
