bronchiectasis vs emphysema radiology

Figure 5a Sarcoidosis in a 35-year-old woman. Rationale and objectives: Bronchiectasis (BE) is associated with chronic obstructive pulmonary disease (COPD), but emphysema and small airways disease, main pathologic features of COPD, have been sparsely studied in BE. A number of features are helpful in diagnosing bronchiectasis 8,9: A number of ancillary findings are also recognized: In general, the treatment of bronchiectasis is medical and involves promoting sputum clearance, using positional physiotherapy, and early and aggressive treatment of pulmonary infections. (2007) ISBN:0781757657. N. Engl. It has a variety of underlying causes, with a common etiology of chronic inflammation. Upper lobe volume loss has worsened, with upward hilar retraction; overall lung volumes were not decreased because of the extensive airtrapping. It is a reliable method of differentiating between obstructive airways disorders (e.g. 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). Although aspiration, chronic infection, and obstructing bronchial lesions are well-recognized causes of bronchiectasis, it is also associated with a number of less common disorders. Movie 2 Cellular mechanisms of bronchiectasis. Recurrent infection and inflammation and the resulting chemical and cellular cascade lead to permanent architectural changes in the airways. As compared with honeycombing, which may present as multiple layers of cysts stacked upon one another, emphysema presents as a single layer of holes without stacking. Singh A, Bhalla AS, Jana M. Bronchiectasis Revisited: Imaging-Based Pattern Approach to Diagnosis. Description. Note that both the right and left heart borders are obscured. This content is not intended to be a substitute for professional medical advice, diagnosis, or treatment. (b) Chest radiograph obtained 5 years later shows that bronchiectasis has progressed, with parallel linear opacities extending along the central upper lobes, representing the tram-track appearance of bronchiectasis. Older women with a thin body habitus are a well-recognized patient phenotype; pectus excavatum chest wall deformity, thoracic scoliosis, and mitral valve prolapse can occur in a subset of patients. Patients with interstitial pneumonia have an increased risk for the development of lung cancer, occurring most frequently in the lower lobes (43). (a) Frontal chest radiograph shows the tram-track appearance of bronchiectasis, with paired parallel linear opacities radiating from the central lungs. Swyer-James Syndrome.—Swyer-James syndrome is a manifestation of postinfectious bronchiolitis obliterans and usually occurs during childhood, with a resultant smaller lucent lung usually accompanied by diffuse bronchiectasis. Common causes of repeated aspiration include large hiatal hernias predisposing patients to gastroesophageal reflux, diseases resulting in a patulous esophagus (including scleroderma), and esophageal motility disorders. (a) Chest radiograph obtained at 19 years of age shows reticular opacities throughout the lungs, representing bronchial wall thickening; mild upper lobe–predominant bronchiectasis is present, and nodular opacities represent mucoid bronchial impaction. In one series, longer exposure to higher inspiratory pressures and high fraction of inspired oxygen correlated with the extent and severity of parenchymal changes noted at imaging (39). The enlargement of the airways is attributable to absence or marked atrophy of the elastic fibers and smooth muscle in the wall of the trachea and main bronchi. Hansell DM, Bankier AA, MacMahon H, McLoud TC, Müller NL, Remy J. Fleischner Society: glossary of terms for thoracic imaging. Figure 16c Mid-order bronchiectasis in the context of Williams-Campbell syndrome in a 50-year-old man with recurrent pneumonia and cough. 7, Current Problems in Diagnostic Radiology, Vol. {"url":"/signup-modal-props.json?lang=us\u0026email="}. Oxford textbook of medicine, Sections 18-33. 42, No. The natural history of the disease involves progressive respiratory decline and increasing severity and frequency of pulmonary infections. Yet, the chances of concurrent COPD and bronchiectasis are slim: while COPD is the third leadin… Note the nodular opacities and volume loss in the right upper lobe; the faint linear opacities represent bronchiectasis. Axial (a, b) and coronal reformatted (c) minimum intensity projection CT images show cystic bronchiectasis limited to the mid-order subsegmental airways. 2002;225 (3): 663-72. Bronchiolitis in graft-versus-host disease has traditionally been associated with bronchiolitis obliterans and is characterized by obstructive physiologic features and mosaic attenuation with airtrapping at CT. (a) Frontal chest radiograph shows the tram-track appearance of bronchiectasis, with paired parallel linear opacities radiating from the central lungs. (2007) ISBN:0781763142. Figure 15a Tracheobronchomegaly (Mounier-Kuhn syndrome). The number of adults with cystic fibrosis has increased over the past few decades; in 1986, only 29.2% of patients with cystic fibrosis were adults, and in 2012, almost half the patients were older than 18 years. 何か見難いと言うご指摘で、①大文字・小文字が入り乱れていたのをエクセルの数式 LOWER=大文字を小文字に や PROPER=先頭の文字だけを大文字に を使用 弊害も出たけど、出来るだけ修正 ②ダブりを修正 ③大拙なのは、医学記事・文献等で見かけた英文字略語を自分なりのノートで … (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. Elevation of the left hemidiaphragm and leftward mediastinal shift accompany the severe left lower lobe volume loss. 3, Journal of Investigative Medicine High Impact Case Reports, Vol. Thorac Surg Clin. 3, 13 December 2016 | Insights into Imaging, Vol. External traction is another mechanism of bronchiectasis and occurs in many fibrosing lung diseases. In cases where bronchiectasis is severe and significant morbidity is present, surgical resection of the affected lobe may be of the benefit provided adequate respiratory reserve exists. 50, No. Cylindrical (or tubular) bronchiectasis, the most commonly identified morphologic type, is a smooth uniform enlargement of bronchi without focal outpouchings or tortuosity. Those with the disease often get frequent lung infections. Three basic morphologic types are recognized at CT: cylindrical, varicose, and cystic. (b) Coronal reformatted CT image shows corresponding dilated bronchi with thickened walls and cylindrical and cystic bronchiectasis. 69, No. Movie 3 Mechanics of bronchiectasis. Bronchiectasis typically presents with recurrent chest infections, productive cough more than 8 weeks, production of copious amounts of sputum, and hemoptysis. Findings are typically more extensive in patients with bronchiectasis due to cystic fibrosis than in patients with bronchiectasis due to other causes. Differences Between Bronchiectasis and COPD . (a) Posteroanterior chest radiograph shows upper lobe–predominant reticulonodular opacities and elevation of both hila due to upper lobe volume loss. In the context of sarcoidosis, severe bronchiectasis is most commonly associated with the end-stage fibrosis characterizing Scadding stage IV disease. 03, Pediatric Allergy, Immunology, and Pulmonology, Vol. Figure 9b (a, b) Rapidly progressing bronchial dilatation and bronchiectasis in a 70-year-old woman with acute respiratory distress syndrome due to pneumonia. The Toronto Lung Transplant Group, Bronchiolitis obliterans syndrome in heart-lung transplant recipients: diagnosis with expiratory CT, CT findings of late-onset noninfectious pulmonary complications in patients with pathologically proven graft-versus-host disease after allogeneic stem cell transplant, Open in Image 3, European Respiratory Review, Vol. Foreign body giant cells and other immune cells are recruited and release free radicals, causing bronchial wall and peribronchial damage, which sometimes leads to lung fibrosis (41). Axial minimum intensity projection CT images show cylindrical bronchiectasis (a), which is seen as a smooth tubular contour and is the most common morphologic type; varicoid bronchiectasis (b), which appears as an undulating irregular contour and often occurs in processes involving fibrosis; and cystic bronchiectasis (c), which is characterized by saccular dilatation of the airways and is classically seen in cystic fibrosis but can occur in many other contexts. Airway epithelium is a source of interleukin-8, which is the principal neutrophil chemoattractant in a lung with cystic fibrosis. High-resolution CT quantification of bronchiectasis: clinical and functional correlation. Enter your email address below and we will send you the reset instructions. The classic form is an upper lobe–predominant cavitary disease similar in radiologic appearance to tuberculosis. ■ Describe the pathophysiologic characteristics of bronchiectasis. The airway dilates in response to an ongoing inflammatory process, causing damage to the airway wall (16). (b) Sagittal reformatted minimum intensity projection CT image shows tubular interconnected airways, a finding that helps distinguish bronchiolectasis from honeycombing or paraseptal emphysema. Of importance, certain atypical mycobacterial infections (such as Mycobacterium avium-intracellulare complex infection) can manifest with upper lobe cavities and bronchiectasis, findings similar to those in tuberculosis. Traction bronchiectasis follows the pattern of fibrosis and is more severe at the lung bases than in the remainder of the lung. In some cases, chronic prophylactic administration of antibiotics may be required. ABPA: glove-finger shadow due to mucoid impaction in central bronchiectasis in a patient with asthma. Bronchiectasis can occur after a prior episode of primary tuberculosis, usually accompanied by other findings such as calcified hilar lymph nodes, calcified parenchymal granulomas, and upper zone volume loss. Emphysema is the predominant component in alpha1-Antitrypsin (α1-AT) Deficiency, but the prevalence and impact of bronchiectasis is greater than previously recognized. Acute exacerbations of bronchiectasis are associated with increased mortality, with decreased forced expiratory volume in 1 second and a history of smoking associated with poor outcomes (7); patients with chronic obstructive pulmonary disease are prone to prolonged exacerbations (8). Infection, aspiration, or another insult, such as bronchiolitis obliterans, can cause direct damage to the bronchial epithelium. (c) Coronal reformatted volume-rendered thick-slab CT image shows extensive bronchiectasis and high-attenuating mucous plugging in the central upper lobes.
