[Pulmonary computed tomography in children with cystic fibrosis in Asturias (Spain)].
BACKGROUND
The advent of computed tomography (CT) has allowed the early detection of pathological changes in patients with cystic fibrosis (CF). Description of the early pathological changes and distribution of bronchiectasis in children with CF is limited, because most studies have been performed in older children and adults with well-established lung disease. The aim of this study was to describe the distribution pattern of this disease in Asturius.


METHODS
We performed a retrospective study of the medical records and CT scans of patients followed up in our Cystic Fibrosis Unit. CT scans were scored by two radiologists according to Bhalla and Nathanson scores. Pathological changes were analyzed and correlated with clinical data and pulmonary function tests.


RESULTS
The 41 CT reviewed contained between 10 and 47 slices, with a median of 16. The total number of slices was 758, of which 606 (79.95%) were considered acceptable and 152 were considered unacceptable by the radiologists. The most frequent lesions found were bronchiectasis (78.38%), followed by mucous plugs (37.84%). The most frequently affected bronchopulmonary segments were S1 and S2 in the right lung. Statistically significant correlations were found between Bhalla and Nathanson scores and disease duration. No statistically significant correlations were found between Bhalla and Nathanson scores and pulmonary function tests.


CONCLUSIONS
The most frequent lesions in our environment were bronchiectasis followed by mucous plugs. The upper right lobe was the first to be affected, which correlates with findings in most published studies.
