  2. Focal lung pneumatosis - Wikipedia

    en.wikipedia.org/wiki/Focal_lung_pneumatosis

    A focal lung pneumatosis is an enclosed pocket of air or gas in the lung and includes blebs, bullae, pulmonary cysts, and lung cavities. Blebs and bullae can be classified by their wall thickness. [1] A bleb has a wall thickness of less than 1 mm. [2] By radiology definition, it is up to 1 cm in total size. [3]

  3. Bleb (medicine) - Wikipedia

    en.wikipedia.org/wiki/Bleb_(medicine)

    Blebs can form in a number of tissues by different pathologies, including frostbite and can "appear and disappear within a short time interval". In pathology, pulmonary blebs are small subpleural thin-walled air-containing spaces, not larger than 1-2 cm in diameter, found by the upper lobe of the lung, between the lung and the visceral pleura ...

  4. Pneumatosis - Wikipedia

    en.wikipedia.org/wiki/Pneumatosis

    In the lungs, emphysema involves enlargement of the distal airspaces, [2] and is a major feature of chronic obstructive pulmonary disease (COPD). Other pneumatoses in the lungs are focal (localized) blebs and bullae, pulmonary cysts and cavities.

  5. Lung surgery - Wikipedia

    en.wikipedia.org/wiki/Lung_surgery

    A bleb resection is the surgical removal of one or more blebs, small collections of air between the lung and visceral pleura. Blebs may combine to form larger cysts named bullae. The rupture of blebs or bullae results in air leaking into the pleural space, causing a spontaneous pneumothorax.

  6. Emphysema - Wikipedia

    en.wikipedia.org/wiki/Emphysema

    When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. [10] [11] Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers ...

  7. Pneumothorax - Wikipedia

    en.wikipedia.org/wiki/Pneumothorax

    It is often called a "collapsed lung", although that term may also refer to atelectasis. [1] A primary spontaneous pneumothorax is one that occurs without an apparent cause and in the absence of significant lung disease. [3] A secondary spontaneous pneumothorax occurs in the presence of existing lung disease.

  8. Pulmonary-renal syndrome - Wikipedia

    en.wikipedia.org/wiki/Pulmonary-renal_syndrome

    Pulmonary-renal syndrome (PRS) is a rare medical syndrome in which respiratory failure involving bleeding in the lungs and kidney failure (glomerulonephritis) occur. [1] PRS is associated with a high rate of morbidity and death. [1] The term was first used by Goodpasture in 1919 to describe the association of respiratory and kidney failure. [1]

  9. Catamenial pneumothorax - Wikipedia

    en.wikipedia.org/wiki/Catamenial_pneumothorax

    Blebs are small blisters/pustules filled with air or fluid and can develop on the lungs. [7] Endometrial tissue attaches within the thoracic cavity, forming chocolate-like cysts. Generally the parietal pleura is involved, but the lung itself, the visceral layer, the diaphragm, and more rarely the tracheobronchial tree may also be
