[目的]研究尘肺病合并特发性间质性肺炎(IIPs)的影像学特点。[方法]对67例尘肺病合并间质性肺炎的影像学资料进行分析,总结其影像学特点。[结果]67例病例中并发59例普通型间质性肺炎(UIP),占88.06%;并发2例非特异性间质性肺炎(NSIP),占2.99%;2例脱屑性间质性肺炎(DIP),占2.99%;1例呼吸性细支气管炎伴间质性肺病(RB-ILD),占1.49%;1例急性间质性肺炎(AIP),占1.49%;1例淋巴细胞间质性肺炎(LIP),占1.49%;1例隐源性机化性肺炎(COP),占1.49%。尘肺合并UIP小阴影以p为主者5例,占8.47%,以s影为主者54例,占91.53%,大阴影为主者1例,占1.69%,以s影为主的尘肺合并UIP较以p影为主的尘肺合并UIP的病例多,差异有统计学意义(P<0.01);尘肺合并IIPs胸片表现以磨玻璃影、网织结节影、蜂窝影等为主;尘肺合并IIPs高分辨率CT(HRCT)表现以磨玻璃影、蜂窝影伴牵引性支气管扩张、小叶间隔增厚等改变为主。HRCT显示,尘肺合并IIPs磨玻璃影、蜂窝影伴牵引性支气管扩张、小叶间隔增厚较胸片明显,差异有统计学意义(P<0.01)。[结论]掌握尘肺病合并IIPs的影像学特点对正确诊断尘肺病以及判断预后有重要意义。
[Objective] To study the imaging features of pneumoconiosis patients with idiopathic interstitial pneumonia (IIPs). [Methods] The imaging data of 67 cases of pneumoconiosis with interstitial pneumonia were analyzed and their imaging features were summarized. [Results] There were 59 cases of common type interstitial pneumonia (UIP) in 67 cases, accounting for 88.06%; 2 cases of non-specific interstitial pneumonia (NSIP), accounting for 2.99%; 2 cases of desquamative interstitial pneumonia (DIP), accounting for 2.99%; 1 case of bronchiolitis bronchiolitis with interstitial lung disease (RB-ILD), accounting for 1.49%; 1 case of acute interstitial pneumonia (AIP), accounting for 1.49%; 1 case of lymphocyte Pneumonia (LIP), accounting for 1.49%; 1 case of cryptogenic organic pneumonia (COP), accounting for 1.49%. Pneumoconiosis with UIP small shadow to p-based in 5 cases, accounting for 8.47%, mainly in s shadow 54 cases, accounting for 91.53%, mainly in 1 case of large shadow, accounting for 1.69%, mainly to s shadow pneumoconiosis UIP had more pneumoconiosis and UIP than p (P <0.01). The pneumoconiosis and IIPs showed pneumoconiosis, reticular nodules and honeycomb, while pneumoconiosis Combined with IIPs high resolution CT (HRCT) performance in the ground glass shadow, cellular shadow accompanied by traction bronchiectasis, lobular septal thickening and other changes based. HRCT showed that pneumoconiosis with IIPs ground glass, honeycomb shadow with traction bronchiectasis, interlobular septal thickening was significantly higher than chest X-ray, the difference was statistically significant (P <0.01). [Conclusion] To master the imaging characteristics of pneumoconiosis patients complicated with IIPs is of great significance for the correct diagnosis of pneumoconiosis and prognosis.
