摘　　要：目的:探讨肺泡蛋白沉积症(PAP)的X线和MSCT影像学表现,以提高对本病的认识和诊断水平。方法:回顾性分析6例经病理及肺泡灌洗证实病例的X线和MSCT表现,探讨其影像学特点,并比较其中1例经全肺灌洗术治疗前后的X线片改变。结果:X线片和MSCT表现为两肺对称或不对称分布的磨玻璃样阴影4例,肺泡实变影2例;MSCT能更清楚地显示磨玻璃中的网格状影(碎石路征)和充气支气管征。1例经全肺灌洗术治疗的PAP,其X线片表现可见明显好转。结论:MSCT可以更清晰显示PAP的病变范围和程度,并且具有典型影像学表现,是PAP首选的诊断方法,X线片对病情有判断价值。Objective：To explore the X-ray and MSCT manifestations of the pulmonary alveolar proteinosis （PAP） and to improve the occuraey of the diagnosis. Methods：Six cases of pulmonary alveolar proteinosis confirmed by pathology or bronchoalveolar lavage were retrospectively reviewed. The imaging features were investigated. The X-ray changes in one case before and after whole lung lavage were analyzed. Results： Both of the chest radiography and MSCT presented symmet- rical or asymmetrical diffuse ground glass opacity in 4 cases,alveolar consolidation was observed in 2 cases. MSCT imaging was better to show reticular shadows of ground glass opacity （crazy-paving sign） and air bronchogram. The chest radio- graphy in one case treated by whole lung lavage showed marked improvement. Conclusion： MSCT can clearly demonstrate the extent of PAP and has typical imaging features, which can be used as preferred diagnostic method. The chest radiograph- y is of value in evaluation of PAP.
