摘　　要：目的:探讨肺泡蛋白沉积症(PAP)支气管肺泡灌洗术(BAL)前后的主要CT表现,以提高对本病的认识及评价BAL后的效果。方法:回顾性分析25例经病理证实为PAP的CT表现,观察病灶的范围、形态、边界及对比BAL前后的变化。结果:PAP的CT表现呈多样化,主要归纳为:地图征、碎石路征、肺水肿样及肺实变征。BAL后15例显著改善。结论:CT能直观显示PAP的影像特征,对该病有较高的诊断价值,同时可评价本病BAL后的效果,确诊依赖病理学证实。Objective： To evaluate the CT imaging features of pulmonary alveolar proteinosis （PAP） before and after bronchoalveolar lavage （BAL）, to raise awareness of the disease and the evaluation of the effect after BAL. Methods： A retrospective analysis of 25 cases of pathologically confirmed was done. The CT imaging features of PAP, including range, shape, boundary, and the changes before and after BAL, were observed. Results： The CT imaging features of PAP were diversified, which summarized as： map sign, gravel levy, pulmonary edema-like symptoms and pulmonary consolidation. 15 cases significantly improved after BAL. Conclusion： CT can visualize the imaging features of PAP and have a higher diagnostic value, that can evaluate the effect after BAL, The diagnosis depends on pathology confirmed.
