What is traction bronchiectasis?
What is traction bronchiectasis?
Traction bronchiectasis is distortion of the airways secondary to mechanical traction on the bronchi from fibrosis of the surrounding lung parenchyma. Although the airways may become dilated in this situation, the other manifestations of bronchiectasis are lacking.
What is pneumonitis hypersensitivity?
Hypersensitivity pneumonitis is an immune system disorder in which your lungs become inflamed as an allergic reaction to inhaled microorganisms, plant and animal proteins or chemicals.
What is Honeycombing of the lungs?
In pathology, honeycomb lung refers to the characteristic appearance of variably sized cysts in a background of densely scarred lung tissue. Microscopically, enlarged airspaces surrounded by fibrosis with hyperplastic or bronchiolar type epithelium are present.
What is the difference between bronchiectasis and traction bronchiectasis?
Bronchiectasis is irreversible dilation of the bronchi resulting from airway damage due to a variety of causes, including infection, airway obstruction, or fibrosis. By definition, traction bronchiectasis results from fibrotic tissue “pulling” on the bronchi, while freestanding bronchiectasis is unrelated to fibrosis.
Is traction bronchiectasis serious?
Conclusions: The presence and severity of traction bronchiectasis/bronchiolectasis are associated with shorter survival. The traction bronchiectasis/bronchiolectasis is an important contributor to increased mortality among subjects with ILA.
How do you know if you have hypersensitivity pneumonitis?
Common symptoms include fever, chills, muscle aches, headache and cough. These symptoms may last for as little as 12 hours to a few days and will resolve if further exposure is avoided. Chronic hypersensitivity pneumonitis develops after numerous or continuous exposures to small amounts of the allergen.
Can honeycomb lung be cured?
No cure exists. Medications may slow down scarring and help preserve lung function. Oxygen therapy and staying active may relieve symptoms.
What is lung reticulation?
Reticulation results from thickening of the interlobular or intralobular septa and appears as several linear opacities that resemble a mesh or a net on HRCT scans. 7. The presence of reticulation is indicative of interstitial lung disease.
