title: High-resolution computed tomography in cystic fibrosis.
abstract: The sensitivity of high-resolution computed tomography (HRCT) in identifying the pulmonary lesions of cystic fibrosis (CF) was evaluated. Thirty-nine patients (16 males, 23 females; mean age 19.1 years) were examined by chest HRCT. According to Shwachman and Kulczycki criteria, the clinical score of the patients ranged from 40 to 95, thus covering most possible variations of lung disease severity. All the patients presented diffuse thickening of bronchial walls, expression of the characteristic CF bronchial inflammation. Bronchiectases were the second most common lung lesions: discrete dilatation of bronchi was observed in 87% of cases; the localization, pattern and extent of bronchiectasis were accurately detected by HRCT. Pleural thickening and hilar adenopathy were frequently identified (in 64% and 82% of the patients, respectively). Bronchoceles were seen in 64% of the patients; atelectasis (33%) and subpleural bullous dystrophic emphysema (28%) were observed less frequently. On HRCT, the localization of the disease processes within the secondary pulmonary lobule was possible in all patients. In agreement with international literature, the identification of these lesions confirms HRCT as the more sensitive technique for early visualization and location of the manifestations of CF bronchopathy. A larger range of experience coming from a systematic use of HRCT in chronic inflammatory lung diseases would increase our knowledge of pathogenetic processes and allow improvement of therapeutic perspectives.
