目的：提高对弥漫性泛细支气管炎（DPB）的认识，探讨高分辨率CT（HRCT）对DPB诊断的应用价值。方法：回顾性分析我院3例确诊为弥漫性泛细支气管炎患者的临床特点及影像表现，其中1例经病理确诊；2例经临床诊断，并复习国内外相关文献资料。结果：弥漫性泛细支气管炎(DPB)的主要HRCT征象特征：①3例均表现为双肺弥漫不均匀分布的小叶中心性结节影，其中2例伴有小斑片状阴影；②2例有树芽征或树上挂雪征；③细支气管扩张；④空气潴留征；⑤肺间质纤维化；⑥2例患者鼻窦CT呈慢性副鼻窦炎表现，且治疗后鼻窦CT显示鼻窦炎有好转。结论：HRCT有助于弥漫性泛细支气管炎的早期诊断和鉴别诊断，并且对治疗预后评价有重要的临床价值。

Objective:To improve the cognition of diffuse panbronchiolitis (DPB) and Investigate the value of HRCT for the diagnosis of Diffuse panbronchiolitis. Methods:A retrospective analysis of three cases of diffuse panbronchiolitis patients with clinical features and CT manifectation, confirmed by pathology and clinical diagnosis in one and two cases respectively, with review of the relevant literatures, Results:The main characteristics of HRCT showed that:①Al cases revealed diffuse centrilobular nodules with uneven distribution, including two cases with smal patchy opacity;②Two cases showed“tree-in-bud”sign;③bronchiolectasis;④peripheral air-trapping;⑤pulmonary interstitial fibrosis; ⑥ The paranasal sinus CT of two cases showed chronic sinusitis, fol owed by obvious improvement after azithomycin treatment . Conclusion : HRCT plays an important role in the diagnosis of DPB especial y in the prognostic evaluation after the therapy.
