目的探讨肺泡蛋白沉积症的CT表现特点,提高对本病的诊断率。方法回顾性分析7例经CT检查并经病理证实的肺泡蛋白沉积症,其中男性5例,女性2例,平均年龄41岁。结果7例均表现为两肺对称或不对称分布弥漫性斑片影和实变影,呈地图样改变。其中6例肺野呈磨玻璃样改变,6例呈铺路石样改变,4例可见支气管充气征。结论 PAP是一种罕见的弥漫性肺实质病变,但其CT表现有一定特征性,再结合临床综合分析就可作出可靠的诊断。

Objective: To analyze the CT features of the pulmonary alveolar proteinosis (PAP), in order to improve the accuracy of diagnosis. Methods: CT findings of PAP in 7 cases confirmed by pathology were retrospectively analyzed. 5 were male and 2 were female, and the average age is 41 years old. Results: Symmetry or dissymmetry diffused patchy cloudy shadows and air-space opacities on two lungs, which were distributed geographically on CT, were all observed in 7 cases. Ground glass shadows in 6 cases. Crazy paving appearance in 6 cases. Air-bronchogram sign in 4 cases. Conclusion:PAP is a rare diffuse pulmonary parenchymal disease. But it is the typical CT features for PAP. Referring to the clinical history and we can made a reliable diagnosis.
