Types of bronchiectasis. Axial CT imaging of three different patients demonstrating the bronchiectasis types. a Cylindrical-type bronchiectasis is characterised by uniform nontapering or gradually tapering bronchial dilatation. b Varicose-type bronchiectasis is characterised by a beaded or “string-of-pearls” appearance with areas of alternating bronchial narrowing and dilatation. c Cystic-type bronchiectasis is characterised by markedly dilated cyst-like bronchi, often extending to the pleural surface with a “cluster-of-grapes” appearance
