摘　　要：目的:探讨27例肺泡蛋白沉积症(PAP)及22例支气管肺泡灌洗术(BAL)后患者的MSCT的表现,旨在提高对本病诊断、鉴别诊断及评价灌洗术后的效果。方法:对27例全部经病理证实的PAP进行回顾性分析,MSCT上观察病灶的形态、范围、边缘及对比灌洗术前后的变化,分析PAP的MSCT表现。结果:PAP在MSCT上表现多样化,可见地图征19例,碎石路征15例,肺水肿样5例,肺实变征7例,伴有微小结节2例,间质纤维化3例;BAL术后20例可显著改善。结论:MSCT能直观显示PAP的影像特征,对诊断有较高的准确性,亦可评价PAP严重程度及随访BAL术后效果。Objective：To probe into MSCT manifestation of pulmonary alveolar proteinosis（PAP） and the radiological changes after bronchial alveolar lavage（BAL）,so as to improve the diagnosis and to evaluate the effect of BAL.Methods：The imaging data of 27 cases with PAP and 22 cases after BAL were retrospectively analyzed.All cases were proved by pathological findings.Results：The imaging findings were various in MSCT,i.e,19 cases showed map sign,15 cases showed crazy-paving sign,5 cases with pulmonary edema,7 cases with pulmonary consolidation,2 cases with small nodules,and 3 cases with interstitial fibrosis.The imaging abnormal improved notably in 20 cases after BAL.Conclusion：MSCT can demonstrate the typical feature of PAP.It is a good method in the diagnosis and the evaluation of the prognosis of PAP.
