摘　　要：目的:探讨肺泡蛋白沉积症(PAP)的高分辨CT(HRCT)特点,提高诊断率。方法:收集5例PAP患者的临床、实验室以及HRCT检查资料,结合国内外文献,对其临床和HRCT表现进行回顾性分析。结果:5例均表现为双肺散在分布的斑片状或大片状磨玻璃影及实变影,边界锐利清晰,呈地图样变4例,3例HRCT显示磨玻璃影中的网格状影(铺路石征)。结论:尽管肺泡蛋白沉积症少见,但其HRCT表现有其特征性,结合临床综合分析,诊断并不难。Objective： To analyze the High-Resolution CT （HRCT）findings of pulmonary alveolar proteinosis （PAP） in an effort to improve the accuracy of diagnosis. Methods：This study included 5 cases of PAP,all patients had complete clinical and laboratory data as well as chest HRCT and clinical and HRCT findings were retrospectively analyzed on the basis of literature review. Results： Among 5 cases ,diffuse flake consolidation and ground-glass shadows were displayed in both lungs,of them, 4 cases with sharply defined margins and geographical appearance, 3 cases showed reticular shadows （crazy paving appearance） . Conclusions： Although PAP is rare, there are some characteristics on HRCT for PAP,associating with clinic data ,we can make diagnosis of PAP.
