摘　　要：目的　分析弥漫性泛细支气管炎 (DPB)的影像学表现 ,探讨其诊断意义。材料与方法 :报道 3例经病理证实DPB。着重分析CT尤其HRCT表现。结果 :DPB的主要HRCT征象 :( 1)小叶中心性结节弥散分布于双肺 ,结节间无融合趋势 ;( 2 )结节近侧端有“Y”字型或线状高密度影与其相连 ;( 3 )结节与胸壁有少许间隔 ;( 4 )小支气管扩张呈管状或环状 ,伴有管壁增厚 ;( 5 )病情进展时 ,结节间的气体贮留明显 ;( 6)结节影、线状影、高密度粘液栓影为可逆性 ,小支气管扩张为不可逆病变。结论 :DPB在中国可能并不罕见 ,影像学尤其CT/HRCT为DPB诊断的主要依据。Objective To analyze the radiologic manifestations of diffuse panbronchiolitis (DPB) and to evaluate these signs in making diagnosis.Materials and Methods CT, especially HRCT, findings in 3 cases with pathologically proved DPB were analyzed.Results The main manifestations of DPB on HRCT were as follows: (1) centrolobular nodules distributed diffusely on both lung fields; (2) linear or “Y” shaped shadows of high attenuation, connecting with the proximal aspect of the nodules; (3) about 2～3mm separation between nodule and thoracic wall; (4) tubular or ring shaped, dilated and wall thickened small airway; (5) marked air trapping sign in the peripheral regions in advanced stage; (6) bronchiolar inflammation, mucus plugging and peri airway thickening were reversible, while airway ectasis was unreversible.Conclusion DPB may not be a rare disease in China. CT, especially HRCT, plays an important role in making diagnosis of DPB.
