At CT, cystic bronchiectasis is limited to the mid-order subsegmental airways, specifically the fourth- to sixth-order bronchi (51) (Fig 16). The main clinical manifestation of bronchiectasis is chronic productive cough (1). (a) Axial CT image (soft-tissue window) shows a soft-tissue mass obstructing the origin of the left lower lobe bronchus. (b, c) Axial (b) and coronal reformatted (c) minimum intensity projection CT images in a 49-year-old man with recurrent pneumonia and Mounier-Kuhn syndrome show severe dilatation of the trachea, main-stem bronchi, and segmental and subsegmental bronchi bilaterally, with a mixed cylindrical, varicoid, and cystic morphologic appearance. Emphysema. (2019) Respirology (Carlton, Vic.). 6. (a) Frontal chest radiograph shows situs inversus totalis with dextrocardia and the stomach in the right upper quadrant of the abdomen. Endobronchial or Peribronchial Tumors.—Slow-growing endobronchial or peribronchial lesions, such as carcinoid tumor, can cause focal bronchiectasis in a lobe, segment, or even a single bronchus (Fig 17). Tree-in-bud nodules related to infection and mucous plugging secondary to impaired clearance are also frequently seen. In one series, central bronchiectasis was uncommon in all causes except allergic bronchopulmonary aspergillosis, in which it was seen in 44% of cases (25).

A bimodal distribution of symptom severity in bronchiectasis has been described, possibly because of greater prevalence of immunodeficiency in young children and older patients, compared with adolescents and younger adults. 14, No. Treatment of most causes of bronchiectasis includes antibiotics for superimposed infections, bronchodilators, nasal oxygen therapy, chest physiotherapy, and inhaled steroids, although the effectiveness of these agents in preventing long-term decline has been questioned (11).
