【摘要】 目的:认识弥漫性泛细支气管炎(DPB)的胸部CT诊断和鉴别诊断价值。方法:回顾性分析2003年6月~2006年10月本院收治的DPB43例,其中病理活检确诊3例,40例临床诊断。结果:DPB的主要胸部CT征象是①弥漫性细粟粒样影伴树芽征,占86.05%,无融合趋势;②小气道细支气管扩张,表现为双轨征和环状透光影,部分病例可见管壁增厚,占67.44%;③炎性斑片影,占53.49%,多为小斑片影。鼻旁窦CT检查多有慢性鼻旁窦炎表现,本组病例占71.43%。结论:CT是DPB诊断中不可缺少的方法,高分辨力CT(HRCT)是胸部CT征象的最佳显示方法,鼻旁窦CT检查可为诊断提供重要佐证。更多还原

【Abstract】 Objective:To analyze the radiologic manifestations of diffuse panbronchiolitis (DPB) and to evaluate these signs in the making of diagnosis.Methods:Fourty-three patients from June 2003 to October 2006 in our hospital were retrospectively analyzed,of which 3 cases were diagnosed pathologically and 40 cases were diagnosed clinically (referring to the second revised diagnostic criteria of Japan).Results:The chest CT appearance of DPB:① 86.05% showed diffuse miliary pulmonary opacities accompanied by tree-in-bud signs,without fusion tendency; ② 67.44% had small bronchiectasis,manifesting small bronchiolar double track signs and small ring-like lucencies,with small bronchial wall thickening in some cases; ③ 53.49% had small inflammatory patchy shadows.Chronic paranasal sinusitis was found by CT examination of paranasal sinuses cavity in 71.43% of all cases.Conclusion:CT is an indispensable method of diagnosing DPB.The chest CT is the main way to show signs for clinical diagnosis,while HRCT is the best choice of thoracic CT.CT examination of accessory nasal cavity may provide significant diagnotic evidence.更多还原
