摘要:
目的分析弥漫性泛细支气管炎（DPB）的多层螺旋CT表现，提高对本病的诊断准确性。 方法回顾性分析本院收治13例弥漫性泛细支气管炎的多层螺旋CT表现。 结果13例中12例病变呈弥漫性分布，1例呈局限性分布。其多层螺旋CT表现：（1）弥漫性细粟粒样影伴树芽征，无融合趋势13例；（2）小气道的支气管扩张12例，合并有黏液栓3例；（3）小斑片状实变影8例、小空洞影2例，肺间质纤维化3例；（4）有副鼻窦炎病史11例，最常累及上颌窦；（5）DPB治疗前后CT变化，经治疗1~3个月后复查，病变有不同程度吸收。 结论DPB的多层螺旋CT表现有一定的特征性，对DPB的诊断具有重要的作用。 Abstract:ObjectiveTo analyze the MSCT features of diffuse panbronchiolitis (DPB) and improve the diagnostic accuracy. MethodsCT features of DPB in 13 patients were retrospectively analyzed. ResultsAmong the 13 cases, the distribution of lesions was bilateral with diffuse in 12 cases and local in 1 case. The chest CT apperances of DPB were as follows:1diffuse small nodules accompanied by tree-in-bud sign in 13 cases; 2small airway bron-Chiectasis in 12 cases, mucoid impaction in 3 cases; 3inflamma-tory patchy consolidation in 8 cases, small cavity in 2 cases, interstitiell fibrosis in 3 cases; 4 Chronic paranasal sinusitis was found by CT examination in 11 cases, mostly involving the maxillary sinus; the changes of CT features before and after treatment; the lesions were absorptive in different degree after treatment 1-3 months later. ConclusionMSCT features of DPB are characteristic, playing an important role in the diagnosis of DPB. -
