摘　　要：目的提高弥漫性泛细支气管炎的CT诊断及鉴别诊断能力。方法回顾性分析我院2001年—2007年收治的83例弥漫性泛细支气管炎的CT表现。结果77例表现为两肺弥漫分布,5例为两肺野内散在斑片状分布,1例局限于两肺下叶。83例均见小叶中心小结节,部分伴有树芽征;54例细支气管扩张,伴有管壁不规则增厚,9例扩张的细支气管内可见黏液栓塞;38例见周围性空气潴留;36例见斑片状影,2例合并右肺中叶不张;肺间质纤维化7例,肺动脉高压7例,合并胸腺瘤和肺癌各1例。结论CT是诊断弥漫性泛细支气管炎的重要依据,结合临床有助于鉴别诊断。Objective To improve cognition for CT manifestations of diffuse panbronchiolitis （DPB）. Methods CT mani-festations of 83 patients with DPB were retrospectively analyzed. Resultes CT revealed bilateral, diffuse lesions in 77 cases, patchy distribution in 5 cases, and in 1 case the nodules localized in both lower lobes. The main CT manifestations of DPB were as following., centrilobular nodule shadow, accompanied with tree-in-bud sign （n= 83）, bronchiectasis with thick walls （n=54）, mucus plugging （n = 9）, peripheral air-trapping （n = 38）, patchy distribution of parenchymal consolidation or ground-glass opacity （n= 36） with right middle lobe ateleetasis in 2 of them, and other signs including complicated with pulmonary interstitial fibrosis or pulmonary hypertension （each n= 7）, as well as thymoma or adenocarcinoma （each n= 1）. Conclusion CT plays an important role in the diagnosis of DPB, being useful in differentiating from other diseases.
