摘　　要：目的 探讨多层螺旋CT（MSCT）对小儿先天大叶性肺气肿（congenital lobar emphysema,CLE）的诊断.方法 搜集经手术病理证实的CLE患儿6例,均行MSCT薄层扫描并进行多平面重组 （multi-planar reconstruction,MPR）及容积再现技术（volume rendering technique,VRT）,结合文献评价MSCT在小儿CLE中的诊断.结果 6例CLE中,位于左上叶2例,右上叶2例,右中上叶2例,均表现为相应肺叶或肺段支气管不同程度狭窄,肺野透亮度增高,体积增大,肺纹理减少.本组伴发右肺支气管扩张、右上叶肺囊肿、右上肺血管发育异常及先天性漏斗胸各1例,右肺多发肺大泡2例,双肺感染3例,纵隔疝4例.结论 MSCT可以直观立体地显示CLE部位、程度及其伴发异常,有利于减少临床误诊和及时治疗.Objective To investigate the diagnostic value of multi-slice spiral CT（MSCT） in congenital lobar emphysema（CLE） in children. Methods Six cases of children with CLE confirmed by surgery pathology were collected in the study. All cases underwent MSCT thin slice scan,CT images were reconstructed with MPR and VRT. MSCT diagnosis of CLE in children was evaluated with literature review. Results The lesions of CLE located at left upper lobe,right upper lobe,right middle and upper lobe in 2 cases,respectively. CT findings included bronchus stenosis in different degrees at corresponding lung segment or lobe, increase of lung radi olucency and volume, reduction of lung markings,and to the accompaniment of bronchiectasis in right upper lung in 1 case,lung cyst in right upper lobe in 1 ease,angiodysplasia in right upper lung in 1 case,congenital funnel chest in 1 case of multiple lung bullae in right lung in 2 cases,infection in bilateral lung in 3 cases and mediastinal hernia in 4 cases. Conclusion MSCT and multi-dimensional reconstruction display directly the location, degree and accompanying anomalies of CLE, which is beneficial for clinic in reducing misdiagnosis and timely treatment.
