目的探讨Swyer-James综合征的CT及高分辨率CT(HRCT)表现。方法19例胸部CT扫描患者,均行HRCT扫描,其中13例有深呼气末及深吸气末HRCT扫描,1例经手术病理证实闭塞性细支气管炎并支气管扩张。结果19例共累及37叶肺,CT显示全部肺叶透亮度增高和肺叶血管纹理细小,其中35叶(95%)容积缩小;同时,CT显示合并支气管扩张19例、肺结核2例、细支气管炎6例和节段性肺不张3例。结论CT及HRCT扫描是诊断该病的较佳方法。 Objective To investigate the CT and high resolution CT (HRCT) features of Swyer-James syndrome. Methods Thirteen patients with chest CT scan underwent HRCT. Among them, 13 patients had end-expiratory and deep end-inspiratory HRCT scans, and 1 patient had obliterative bronchiolitis with bronchiectasis confirmed by surgery and pathology. Results Of the 19 cases, 37 lobes were involved. CT showed that all of the lobes were bright and the lung lobes were finely textured. The volume of the 35 lobes was reduced (95%). CT showed bronchiectasis in 19, tuberculosis in 2, bronchiolitis 6 Cases and segmental atelectasis in 3 cases. Conclusion CT and HRCT scan is a better way to diagnose the disease.
