摘要
目的探讨肺泡蛋白沉着症(PAP)的影像学特征以协助诊断。方法对19例经肺泡灌洗或纤维支气管镜活检证实的肺泡蛋白沉着症患者的CT表现进行回顾性分析,并回顾复习有关文献。结果 PAP胸部影像表现呈多样化,可归纳为磨玻璃影、不规则斑片影以及肺间质改变样表现等。当磨玻璃影和不规则斑片影同时出现时高度提示为PAP。结论当CT/HRCT影像学表现为典型的中下肺野为重的磨玻璃影,合并于周围正常肺组织分界清楚的不规则斑片影,结合临床不难做出肺泡蛋白沉着症的正确诊断。
Objective To analyze the radiological features and the diagnostic method of pulmonary alveolar proteinosis（PAP）. Methods The CT manifestations of PAP in 19 cases confirmed by using bronehoalveolar lavage and fiberoptic bronehoseopy and the related literatures were studied retrospectively. Results The radiologieal features of PAP showed the ground glass -like shadow and irregular patches and the interstitial fibrosis- like change. When the ground glass-like shadow and irregular patches appeared at the same time, it highly suggested PAP. Conclusion The typical radiologieal features of PAP are ground glass-like shadow in the middle and lower lung field and distinguished irregular patches, it is not difficult to make a diagnosis in combination with its clinical characteristics.
