Axial (a, b) and coronal reformatted (c) minimum intensity projection CT images show cystic bronchiectasis limited to the mid-order subsegmental airways. ABPA: glove-finger shadow due to mucoid impaction in central bronchiectasis in a patient with asthma. (2019) Respirology (Carlton, Vic.). The association between α1-antitrypsin deficiency and premature development of panlobular emphysema is well recognized. The Baylor Medicine Spine Center provides the full continuum of care for patients experiencing back and neck pain. Several categories of nontuberculous mycobacterial infection are recognized. The classic diagnostic triad in patients with cystic fibrosis includes an abnormal sweat chloride test result and manifestations of pulmonary and pancreatic disease (27). Nodular opacities throughout the lungs correlate with areas of mucoid bronchial or bronchiolar impaction. Bronchiectasis is irreversible dilation of the bronchi resulting from airway damage due to a variety of causes, including infection, airway obstruction, or fibrosis. Chronic Obstructive Pulmonary Disease is a progressive disorder and there is no cure for it. In patients with α1-antitrypsin deficiency who develop bronchiectasis, the distribution tends to follow the emphysematous changes, with greater severity in the lower lungs (49). both bronchiectasis and emphysema are classifed as chronic obstructive pulmonary diseases (COPD) emphysema mainly is the problem with the elastic recoil of the lung. Note the normal caliber of the trachea and proximal bronchi, an appearance compatible with Williams-Campbell syndrome. At chest radiography, a markedly dilated trachea and central bronchi can be seen (Fig 15). 4, 6 June 2018 | QJM: An International Journal of Medicine, Vol. (b, c) Axial CT images near the apices (b) and slightly more inferior (although still above the carina) (c) shows central symmetric upper lobe distribution of bronchiectasis with associated peribronchovascular architectural distortion (“bronchial clumping”) and ground-glass opacities. (b, c) Axial CT images near the apices (b) and slightly more inferior (although still above the carina) (c) shows central symmetric upper lobe distribution of bronchiectasis with associated peribronchovascular architectural distortion (“bronchial clumping”) and ground-glass opacities. A “finger-in-glove” pattern can be seen at chest radiography that corresponds to mucoid bronchial impaction at chest CT (Fig 6). Traction bronchiectasis in end-stage pulmonary fibrosis. Irregularity of the tracheal wall is attributable to laxity of the tracheal cartilage in this disorder. It first appears too complicated to read the chest xrays because we barely know what lies where and what to make out of it. Bronchiectasis is more common in patients with α1-antitrypsin deficiency than was previously thought and rarely appears before emphysema (33). 246 (3): 697-722. Imaging plays a pivotal role in the diagnosis of bronchiectasis. 6, © 2021 Radiological Society of North America, The pathophysiology of bronchiectasis, Impaired tracheobronchial clearance in bronchiectasis, Progression of lung disease on computed tomography and pulmonary function tests in children and adults with cystic fibrosis, Chest computed tomography scores of severity are associated with future lung disease progression in children with cystic fibrosis, Cystic Fibrosis Foundation Patient Registry Report 2012, Mortality in non-cystic fibrosis bronchiectasis: a prospective cohort analysis, Predictors of mortality in hospitalized patients with acute exacerbation of bronchiectasis, Bronchiectasis, exacerbation indices, and inflammation in chronic obstructive pulmonary disease, Characterisation of the onset and presenting clinical features of adult bronchiectasis, Hemoptysis: etiology, evaluation, and outcome in a tertiary referral hospital, Factors associated with lung function decline in adult patients with stable non-cystic fibrosis bronchiectasis, Current surgical therapy for bronchiectasis: surgical results and predictive factors in 86 patients, Fleischner Society: glossary of terms for thoracic imaging, Mechanical ventilation and lung infection in the genesis of air-space enlargement, Reduction in bronchial subdivision in bronchiectasis, Inflammation: a two-edged sword—the model of bronchiectasis, Mucosal inflammation in idiopathic bronchiectasis: cellular and molecular mechanisms, A study of the pathology and pathogenesis of bronchiectasis, Traction bronchiectasis in end-stage pulmonary fibrosis, CT of airways disease and bronchiectasis, High-resolution CT of the lung: patterns of disease and differential diagnoses, Thin-section CT of the lungs: the hinterland of normal, Lung morphology in the elderly: comparative CT study of subjects over 75 years old versus those under 55 years old, Bronchiectasis: accuracy of high-resolution CT in the differentiation of specific diseases, Upper lobe-predominant diseases of the lung, Airway inflammation in cystic fibrosis, Pulmonary sarcoidosis, Sarcoidosis with pulmonary fibrosis: CT patterns and correlation with pulmonary function, Pulmonary sarcoidosis: evaluation with high-resolution CT, Clinical significance of hyperattenuating mucoid impaction in allergic bronchopulmonary aspergillosis: an analysis of 155 patients, Bronchiectasis in patients with α, CT of tuberculosis and nontuberculous mycobacterial infections, Nontuberculous mycobacterial pulmonary infections, An official ATS/IDSA statement: diagnosis, treatment, and prevention of nontuberculous mycobacterial diseases, Pulmonary nontuberculous mycobacterial infection: radiologic manifestations, The American-European Consensus Conference on ARDS: definitions, mechanisms, relevant outcomes, and clinical trial coordination, Air cysts and bronchiectasis prevail in nondependent areas in severe acute respiratory distress syndrome: a computed tomographic study of ventilator-associated changes, Acute respiratory distress syndrome: imaging of the injured lung, Importance of diffuse aspiration bronchiolitis caused by chronic occult aspiration in the elderly, Idiopathic interstitial pneumonias: CT features, Association of malignancy with diseases causing interstitial pulmonary changes, Nonspecific interstitial pneumonia/fibrosis: histologic features and clinical significance, Diagnosis and management of primary ciliary dyskinesia, Detection of pulmonary complications in common variable immunodeficiency, Comparison of pulmonary diseases in common variable immunodeficiency and X-linked agammaglobulinaemia, Prevalence and impact of bronchiectasis in α, Tumors and tumorlike conditions of the large airways, Williams-Campbell syndrome: a case report, Imaging of small airway disease (SAD), Unilateral hyperlucent lung in children, Bronchiolitis obliterans syndrome leads to a functional deterioration of the acinus post lung transplant, Stanford experience with obliterative bronchiolitis after lung and heart-lung transplantation, Bronchiolitis obliterans after lung transplantation: findings at chest radiography and high-resolution CT.

Two groups make up the majority of cases: post-infectious and cystic fibrosis 3. Traction varicoid bronchiectasis can have an anterior distribution (right middle lobe and lingula), with associated areas of parenchymal scarring. Bronchiectasis may mimic cystic lung disease and bullous emphysema. (d) Coronal reformatted minimum intensity projection CT image shows bilateral symmetric upper lobe cylindrical and varicoid bronchiectasis. (a) Axial CT image (lung window) shows ectatic bronchi filled with mucus and fluid; a few aerated thick-walled bronchi are visible in the right upper lobe. Both emphysema and bronchiectasis can significantly interfere with the lungs function, making it more difficult to breathe. (b) Axial minimum intensity projection CT image obtained 5 weeks later, after a prolonged hospital stay and progressively higher oxygen requirements necessitating mechanical ventilation, shows progression of bronchiectasis, now with varicoid morphologic features. For this journal-based SA-CME activity, the authors, editor, and reviewers have disclosed no relevant relationships. Cystic fibrosis is perhaps the most recognized cause of bronchiectasis and is associated with substantial morbidity and mortality. Infection leads to impaired ciliary function, limiting the ability of the airway to clear harmful organisms and inflammatory substances. Combination of fibrotic lesions with Bronchiectasis is seen as comorbidity in patients with more common respiratory diseases most notably in those with more severe asthma and chronic obstructive pulmonary disease (COPD). Less frequently, α1-antitrypsin deficiency is associated with the development of bronchiectasis; however, α1-antitrypsin deficiency affects the airways through abnormal elastase or anti-elastase balance, leading to chronic airway diseases including chronic bronchitis and bronchiectasis (48). Figure 19 Bronchiolitis obliterans with diffuse bronchiectasis several years after bilateral lung transplantation in a 67-year-old man. Mechanisms may involve both parenchymal damage intrinsic to acute respiratory distress syndrome and barotrauma resulting from prolonged mechanical ventilation. 7, Current Problems in Diagnostic Radiology, Vol. As a result, patients are predisposed to repeated infections, airway damage, and bronchiectasis. Pulmonary M avium-intracellulare infection is difficult to eradicate; treatment includes a multidrug regimen typically prescribed for at least 1 year (36). Findings are typically more extensive in patients with bronchiectasis due to cystic fibrosis than in patients with bronchiectasis due to other causes. α1-Antitrypsin Deficiency.—Another less common cause of bronchiectasis is α1-antitrypsin deficiency. In the context of sarcoidosis, severe bronchiectasis is most commonly associated with the end-stage fibrosis characterizing Scadding stage IV disease. The signet ring sign is a primary finding of bronchiectasis at CT and refers to the cross section of a dilated air-filled bronchus adjacent to a smaller nodular opacity representing the accompanying pulmonary artery (13) (Fig 1). Treatment of frequent pulmonary infections is supportive, and the only definitive therapy is lung transplantation, which is limited by donor lung availability. Due to their multi-dimensional character and simplicity, these scores are … The majority of deaths were related to respiratory infection, with higher mortality rates associated with increasing age and number of lobes affected. Figure 7a Tuberculosis in a 29-year-old man with mild weight loss. Bronchiectasis represents both an important potential cause of morbidity (usually associated with recurrent infection and related complications) and a valuable indicator of underlying pulmonary disease. 2 causes for emphysema . These findings are typical in Swyer-James syndrome, an asymmetric bronchiolitis obliterans usually caused by an infectious insult during lung development. 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). In one series, central bronchiectasis was uncommon in all causes except allergic bronchopulmonary aspergillosis, in which it was seen in 44% of cases (25). 8, No. (c, d) Axial (c) and coronal reformatted (d) minimum intensity projection CT images obtained 2 years later (at 26 years of age) show extensive cystic and varicoid bronchiectasis in the upper lobes.
