肺泡蛋白沉着症支气管肺泡灌洗术前后胸部CT主要表现

The CT Imaging Features of Pulmonary Alveolar Proteinosis Before and After Bronchoalveolar Lavage

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。

Abstract: 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.
