Bronchoceles are characterized by the abnormal dilation of a
bronchus that becomes filled with mucus, often resulting from an
obstruction that prevents mucus drainage. It is commonly
associated with congenital lung conditions like bronchial atresia, or
acquired conditions such as bronchial tumors or post-infectious
scarring. The pathogenesis involves blockage of the airway, leading
to mucus accumulation and dilatation of the bronchus. Diagnosis is
usually confirmed with imaging, particularly CT scans, where a
bronchocele appears as a tubular or branching structure with a
“finger-in-glove” appearance, filled with mucus. (Etesami)
