摘要
目的:探讨多层螺旋CT(MSCT)对婴幼儿闭塞性细支气管炎(BO)影像分型和分期的应用价值。方法:回顾性分析28例2012年8月至2015年8月儿科住院的婴幼儿BO临床和影像资料,探讨BO的CT分型,并分析不同时期的影像表现。结果:本组患儿急性期MSCT均表现为肺部马赛克征、细支气管壁增厚,合并肺不张6例。CT分型:单纯型18例,肺炎型10例。治疗2~4周后复查:20例肺部恢复正常,8例转入慢性期,表现为肺间质纤维化7例、支气管扩张6例、支气管末梢钙化3例及胸膜粘连2例。结论:MSCT马赛克征是闭塞性细支气管炎早期的特征性征象,CT分型和分期有助于指导临床治疗。
Objective To explore the value of multi-slice computed tomography （MSCT） on the typing and staging of bronehiolitis obliterans （BO） in children. Methods Twenty-eight BO patients were recruited and underwent X-ray and MSCT from August 2012 to August 2015. The classification of MSCT signs and radiological manifestations in different stages of BO were discussed. Results Mosaic sign and bronchial wall thickening appeared in all cases and pulmonary ateleetasis in 6 patients. MSCT signs were divided into 18 cases of simple type and 10 of pneumonic type, respectively. Radiologieal imaging undergone after treatment for 2 ~ 4 weeks indicated that 20 patients turned normal, but 8 patients to chronic stage, including pulmonary interstitial fibrosis （7 cases）, bronehoieetasis （6 cases） , calcification in bronchial distal （3 cases） and pleural adhesions （2 cases）. Conclusion Mosaic sign is a distinctive MSCT manifestation for BO in early phase, and CT typing and staging contribute to guiding the treatment.
