目的分析特发性单侧透明肺的影像诊断。方法本组共29例特发性单侧透明肺。29例均拍胸部正侧位片,其中19例行电视透视,14例行胸部CT扫描,2例做支气管造影,1例行体层摄影,1例行肺动脉、主动脉造影。结果29例患肺透亮度增大,其中左全肺23例,左下叶5例,左全肺并右肺中下叶1例。左肺门及肺血管性纹理细小。21例左侧胸廓轻度塌陷,21例纵隔气管左偏,19例电视透视见纵隔摆动,14例CT扫描见左肺动脉细小,其中主干细小9例,左肺下叶动脉细小5例。12例见右下肺动脉干增粗,5例动脉段延长,7例肺动脉段突出,4例心脏增大,19例支气管扩张。结论影像学检查是特发性单侧透明肺的关键确诊手段。
Objective To analyze the imaging diagnosis of idiopathic unilateral transparent lung. Methods This group a total of 29 cases of idiopathic unilateral transparent lung. Twenty-nine patients underwent chest radiography, including 19 cases of TV fluoroscopy, 14 cases of chest CT scan, 2 cases of bronchography, 1 case of tomography, and 1 case of pulmonary artery and aortography. Results In 29 cases, the brightness of the lung increased, including 23 cases of left lung, 5 cases of left lower lobe, 1 case of left and right lower lobe. Left hilar and pulmonary vascular texture is small. Twenty-one patients had mild left-sided thoracic collapse, 21 left-lateral mediastinal trachea, 19 mediastinoscopy with mediastinum swing, and 14 CT scans with small left pulmonary arteries, including 9 with small trunk and 5 with inferior left lobe artery. In 12 cases, the right lower pulmonary artery thickening, 5 cases of arterial extension, 7 cases of prominent pulmonary artery, 4 cases of cardiac enlargement and 19 cases of bronchiectasis. Conclusion Imaging examination is the key diagnostic tool for idiopathic unilateral transparent lung.
