Preferred Label : bronchocele;
Definition : Pathology.—A bronchocele is bronchial dilatation due to retained secretions (mucoid
impaction) usually caused by proximal obstruction, either congenital (eg, bronchial
atresia) or acquired (eg, obstructing cancer) (34). Radiographs and CT scans.—A bronchocele
is a tubular or branching Y- or V-shaped structure that may resemble a gloved finger
(Fig 13). The CT attenuation of the mucus is generally that of soft tissue but may
be modified by its composition (eg, high-attenuation material in allergic bronchopulmonary
aspergillosis). In the case of bronchial atresia, the surrounding lung may be of decreased
attenuation because of reduced ventilation and, thus, perfusion. [Fleischner Society];
