  3. 3. bronchiectasisBronchiectasis is irreversiblelocalized or diffuse bronchial dilatation,usually resulting from chronic infection,proximal airway obstruction, orcongenital bronchial abnormality
  4. 4. signet ring signThis finding iscomposed of a ring-shaped opacityrepresenting a dilatedbronchus in crosssection and a smalleradjacent opacityrepresenting itspulmonary artery, withthe combinationresembling a signet (orpearl) ring
  5. 5. bronchoceleA bronchocele is bronchialdilatation due to retained secretions(mucoid impaction) usually caused byproximal obstruction, either congenital(eg, bronchial atresia) or acquired (eg,obstructing cancer)
  6. 6. bronchocentricThis descriptor is applied todisease that is conspicuously centered on macroscopic bronchovascular bundlesExamples of diseases witha bronchocentric distribution include :sarcoidosis , Kaposi sarcoma ,and organizing pneumonia .
