【摘要】：目的:探討多層螺旋CT(MSCT)對嬰幼兒閉塞性細支氣管炎(BO)影像分型和分期的應(yīng)用價值。方法:回顧性分析28例2012年8月至2015年8月兒科住院的嬰幼兒BO臨床和影像資料,探討B(tài)O的CT分型,并分析不同時期的影像表現(xiàn)。結(jié)果:本組患兒急性期MSCT均表現(xiàn)為肺部馬賽克征、細支氣管壁增厚,合并肺不張6例。CT分型:單純型18例,肺炎型10例。治療2~4周后復(fù)查:20例肺部恢復(fù)正常,8例轉(zhuǎn)入慢性期,表現(xiàn)為肺間質(zhì)纖維化7例、支氣管擴張6例、支氣管末梢鈣化3例及胸膜粘連2例。結(jié)論:MSCT馬賽克征是閉塞性細支氣管炎早期的特征性征象,CT分型和分期有助于指導(dǎo)臨床治療。
[Abstract]:Objective: to evaluate the value of multi-slice spiral CT (MSCT) in (BO) classification and staging of infant occlusive bronchiolitis. Methods: the clinical and imaging data of 28 infants and young children hospitalized in pediatrics from August 2012 to August 2015 were analyzed retrospectively. the CT classification of BO was discussed and the imaging findings in different periods were analyzed. Results: in the acute phase of the children, MSCT showed pulmonary mosaic sign, thickening of bronchiole wall and atelectasis in 6 cases. Ct classification: simple type 18 cases, pneumonia type 10 cases. After 2 weeks of treatment, 20 cases of lung returned to normal, 8 cases of chronic phase, 7 cases of pulmonary fibrosis, 6 cases of bronchiectasis, 3 cases of bronchial calcification and 2 cases of pleura adhesion. Conclusion: MSCT mosaic sign is a characteristic sign in the early stage of bronchiolitis obliterans. CT classification and staging are helpful to guide clinical treatment.
