“…Plain radiographs show areas of chronic collapse, air-fluid levels characteristic of lung abscess, or signs of bronchiectasis. High resolution CT scan is currently the modality of choice in the diagnosis of broncheicatsis with only 2% false negative and 1% false positive rate [7,8]. In this series, a preoperative CT scan was obtained in all cases.…”

Lung resection is uncommon in children because of its limited indications. We reviewed and analyzed the records of 31 children who underwent pulmonary resection between 1994 and 2001. The mean age was 7 years (range 1.6-12 years), and genders were equal. Bronchiectasis, lung abscess, necrotizing pneumonia, and destroyed lung were seen in 14, 12, 3, and 2 patients, respectively. Bronchial stenosis and inflammation of the bronchus was found endoscopically in four patients, and a foreign body in one patient. The indications for surgery in chronic sepsis were: recurrent respiratory tract infections, severe bronchiectasis, recurrent hemoptysis, destroyed lung parenchyma, and lung abscess, while the indications for surgery in acute infections were: failed medical treatment, or empyema. A lobectomy was done on 15 patients, lobectomy and lingulectomy on 4, lobectomy and decortications on 10, and pneumonectomy on 2 with no operative deaths. Intra-operative and post-operative complications were seen in 2 and 4 patients, respectively. Mean follow-up was 3.9 years (range 1.5-5 years). Twenty-eight patients were asymptomatic and three had improved. Respiratory function remained unchanged in 14 children. Mediastinal shift and lung overinflation occurred after pneumonectomy. These results show that lung resection can be done safely in pulmonary infection refractory to conservative medical therapy. Pulmonary resection does not alter respiratory function since the resected segments do not contribute to ventilation.

“…These scoring systems have been applied in several diseases [35][36][37][38][39][40][41][42][43][44][45]. Scoring systems rely on the subjective detection and grading of direct and indirect signs of airway disease, such as airway wall thickening, bronchiectasis, mosaic perfusion and/or gas trapping [46][47][48][49][50]. However, qualitative studies are sensitive to the display settings (window width and level) of the images, are prone to inter-and intra-reader variability, and are time consuming and, therefore, expensive.…”

Alterations in the structure of the airways, collectively termed airway remodelling, contribute to airflow obstruction in a variety of chronic lung diseases. While histology has provided valuable insights into the structure of airway wall remodelling, this technique is invasive and does not allow the longitudinal analysis of airway wall dimensions. Technical advances in computed tomography allow the assessment of airway wall dimensions, and are ideally suited for the noninvasive investigation of the pathogenesis of airway wall remodelling and the evaluation of new therapeutic interventions. The aim of this article is to review the use of computed tomography in the investigation of airway structure and function in health and disease.

“…Bronchography, traditionally considered the investigation of choice for the diagnosis of bronchiectasis, is not only invasive but may also be associated with adverse effects [9] . HRCT of the chest safely allows detection of abnormalities not apparent on chest radiography with a sensitivity and specificity of 96%-98% and 93%-99% respectively, compared to bronchography in diagnosis of bronchiectasis [10,11] . The chest radiographic findings depend on the clinical stage of the disease.…”

AIM:To investigate the chest radiographic and high resolution computed tomography (HRCT) chest manifestations in glucocorticoid-naïve allergic bronchopulmonary aspergillosis (ABPA) patients. METHODS:This is a prospective observational study and includes 60 consecutive glucocorticoid-naïve patients with ABPA who underwent chest radiography and HRCT of the chest (1.25 mm every 10 mm) in the routine diagnostic workup for ABPA. RESULTS:Chest radiographs were normal in 50% of cases. Of the remainder, most patients demonstrated permanent findings in the form of parallel line and ring shadows suggesting bronchiectasis. Consolidation was detected in 17 cases but in the majority, the corresponding HRCT chest scan showed mucus-filled bronchiectatic cavities. Chest HRCT was normal in 22 patients, while central bronchiectasis (CB) was demonstrated in the remaining 38 patients. Bronchiectasis extended to the periphery in 33%-43% depending on the criteria used for defining CB. The other findings observed on HRCT were mucoid impaction, centrilobular nodules and high-attenuation mucus in decreasing order of frequency. CONCLUSION:Patients with ABPA can present with normal HRCT chest scans. Central bronchiectasis cannot be considered a characteristic feature of ABPA as peripheral bronchiectasis is commonly observed. Consolidation is an uncommon finding in ABPA.
