多层螺旋CT对弥漫性泛细支气管炎的诊断价值

Multislice spiral CT of diffuse panbronchiolitis diagnostic value

目的探讨多层螺旋CT(MSCT)对弥漫性泛细支气管炎(DPB)的诊断和鉴别诊断价值。方法回顾性分析我院2007年5月至2012年6月收治的经临床或病理证实的11例DPB的CT表现,并结合文献加以总结。结果病灶呈弥漫性分布9例,呈局限性分布2例;弥漫性细粟粒样小结节影11例,8例伴有树芽征;细支气管扩张9例,伴有管壁不规则增厚,合并有黏液栓2例;炎性斑片状影5例,多为小斑片影,合并小空洞影1例、节段性肺不张2例;空气潴留征4例;肺间质纤维化2例;肺动脉高压1例;有慢性副鼻窦炎表现者7例;DPB治疗2个月后复查,病变有不同程度吸收6例。结论 DPB的MSCT表现具有一定的特征,副鼻窦炎病史有助于鉴别诊断,确诊依赖病理学检查。

Objective To evaluate the value of multislice spiral CT of diffuse panbronchiolitis （DPB） in the di agnosis and differential diagnosis. Methods A retrospective analysis of CT findings of 11 cases in our hospital from May 2007 to June 2012, who were clinically or pathologically confirmed of DPB and related literature to summarize. Results It showed diffuse distribution of lesions in 9 cases, and localized distribution in 2 cases,diffuse miliary fine small nodules in 11 cases, 8 cases with tree bud; bronchiolectasis in 9 cases, associated with irregular wall thickening , while bronchiolectasis associated with mucus plug in 2 cases; inflammatory patchy shadow in 5 cases, mostly with small patches of shadow, 1 case with small cavities, segmental atelectasis in 2 cases; pulmonary interstitial fibrosis in 2 cases; pulmonary hypertension in 1 case; manifestations of chronic sinusitis showed in 7 cases; 6 eases were re viewed two months after treatment, and all the lesions have varying degrees of absorption. Conclusion Muhislice spi ral CT manifestations of DPB has certain characteristics, sinusitis history is useful in differential diagnosis, and final diagnosis depends on pathological examination.
