摘    要:目的探讨结节病肺部改变的CT表现及特征。方法回顾性分析90例经手术病理证实的结节病的临床资料及CT表现。结果结节69例(76.7%),主要沿支气管血管束分布37例(41.1%),团块影31例(34.4%),磨玻璃影39例(43.3%),支气管血管束增粗30例(33.3%),小叶间隔线58例(64.4%),纤维化17例(18.9%),包括支气管变形8例(8.9%)、条索影5例(5.6%)、蜂窝影4例(4.4%),空气潴留3例(3.3%),支气管狭窄8例(8.9%),胸膜改变42例(46.7%),肺门纵隔淋巴结增大76例(84.4%)。2种及2种以上肺部病变并存83例(92.2%),肺部病变合并肺门纵隔淋巴结增大76例(84.4%)。结节、团块、磨玻璃影、支气管血管束增粗治疗后随访吸收好转例数分别为25例(25/30)、9例(9/15)、11例(11/16),10例(10/12);小叶间隔线、支气管变形、条索影、蜂窝影吸收好转例数分别为10例(10/22)、0例(0/4)、1例(1/3),0例(0/2)。结论结节病肺部CT表现形式多样,具有一定特征性,同时结合肺门纵隔淋巴结增大改变,有助于提高诊断正确率。

Abstract:Objective To investigate the CT features of pulmonary sarcoidosis.Methods Ninety patients with histologically proved pulmonary sarcoidosis were retrospectively studied by using CT scans and clinical recording.Results The main CT findings of pulmonary sarcoidosis were nodules which were seen in 69 cases(76.7%),and the nodules mostly distributed around the bronchovascular bundle(n=37, 41.1%).Other abnormalities included consolidation(n=31,34.4%),ground-grass(n=39,43.3 %), thickening of bronchovascular bundle(n=30,33.3%),interlobular septal lines(n=58,64.4%), fibrosis(n=17,18.9%)including bronchial distortion(n=8,8.9%),linear shadow(n=5,5.6%), and honeycombing shadow(n=4,4.4%),air-trapping(n=3,5.3%),bronchial straitness(n=8, 8.9%),pleural thickening(n=42,46.7%),and hilar and mediastinal adenopathy(n=76,84.4%). Two or more abnormal findings co-existed in 83 cases.The pulmonary lesions co-existed with hilar and mediastinal adenopathy in 76 cases.The nodules(n=25),consolidation(n=9),ground-grass(n=11), thickening of bronehovascular bundle(n=10)were improved after therapy.Ten cases of the interlobular septal(10/22),0 of bronchial distortion(0/4),1 case of diffuse linear(1/3),and 0 case of honeycombing(0/2)were improved.Conclusion CT manifestations of pulmonary sarcoidosis are varied, but has some specific radiographic features.A correct diagnosis can be made.combined with hilar and mediastinal adenopathy.
