Preferred Label : bronchiectasis;
Definition : Pathology.—Bronchiectasis is irreversible localized or diffuse bronchial dilatation,
usually resulting from chronic infection, proximal airway obstruction, or congenital
bronchial abnormality (26). (See also traction bronchiectasis.) Radiographs and CT
scans.—Morphologic criteria on thin-section CT scans include bronchial dilatation
with respect to the accompanying pulmonary artery (signet ring sign), lack of tapering
of bronchi, and identification of bronchi within 1 cm of the pleural surface (27)
(Fig 11). Bronchiectasis may be classified as cylindric, varicose, or cystic, depending
on the appearance of the affected bronchi. It is often accompanied by bronchial wall
thickening, mucoid impaction, and small-airways abnormalities (27–29). (See also signet
ring sign.) [Fleischner Society];
