The diagnostic value of multislice computed tomography in children with congenital lobar emphysema

Abstract

Objective: To investigate the diagnostic value of multislice computed tomography (MSCT) in children with congenital lobar emphysema (CLE). Materials & methods: Seven children with CLE diagnosed by surgery pathology had undergone thin-slice scanning of MSCT, multiplanar reconstruction and volume rendering technique. The diagnostic value of MSCT in children with CLE was evaluated. Results: Among seven patients with CLE, three cases were located in the left upper lobe, two cases in the right upper lobe and two cases in the right middle-upper lobe. All cases were manifested by variable degrees of bronchus stenosis in the corresponding lung segment or lobe, increased lung radiolucence and volume, and reduced lung markings. In this group, there was one case, respectively, associated with left posterior mediastinal bronchogenic cyst, bronchiectasis in the right lung, a lung cyst in the right upper lobe, angiodysplasia in the right upper lung and congenital funnel chest; two cases of multiple lung bullae in the right lung, three cases of infection in both lungs and four cases of mediastinal hernia. Conclusion: MSCT and multidimensional reconstruction is a noninvasive diagnostic method that displays the location, degree and accompanying anomalies of CLE in three dimensions. It has significance for clinicians in that it reduces both misdiagnosis and the time taken to receive treatment.
