2024年3月7日 · The term bronchocele indicates focal bronchial dilatation and is often associated with mucoid impaction and impaired ventilation. Bronchoceles can be congenital (e.g. bronchial atresia) or acquired due to retained secretions or proximal …

Bronchoceles represent impacted mucoid secretions within the bronchial tree. The cause can be divided by whether they result from obstruction or not. Obstructive causes include tumor, stricture or foreign body. Non-obstructive causes include asthma, cystic fibrosis and ABPA.

2024年12月19日 · Mucoid impaction, also referred to as mucus plugging, refers to airway filling by retained secretions. When the bronchi become dilated due to mucoid impaction, the term bronchocele can be used 6. Mucoid impaction may result from either obstructive or non-obstructive causes, although the latter does eventually obstruct the bronchi as well:

2008年9月1日 · Both congenital and acquired abnormalities may cause mucoid impaction of the large airways that often manifests as tubular opacities known as the finger-in-glove sign. The congenital conditions in which this sign most often appears …

2010年2月25日 · There may be air trapping and lucency distal to the bronchocele. Sometimes the obstructing lesion produces lung collapse, making it impossible to identify the bronchocele on CXRs. CT – confirms the plain film changes with dilated mucus-filled bronchi ± distal air trapping.

Bronchocele (bronchial mucocele) refers to a mucous-filled and dilated bronchus surrounded by aerated lung. These can be the result of an obstructive lesion to the bronchial tree as in congenital bronchial atresia where they usually affect the apicoposterior segment of the left upper lobe.

2016年10月15日 · The classic findings in the chest X-ray of bronchocele caused by bronchial atresia is a lobed, branching tubular or nodular opacity that extends from the hilum with surrounding hyperlucent lung parenchyma.
