目的探讨肺泡蛋白沉着症(PAP)的影像特征及诊断方法。方法对37例经纤维支气管镜活检或开胸活检病理及肺泡灌洗证实的原发性肺泡蛋白沉着症患者的胸片和CT表现进行回顾性分析。结果PAP胸部影像表现呈多样化,可归纳为地图样表现、碎石路样表现、肺实变表现(支气管充气征)以及肺间质纤维化样表现等。肺部阴影重且相对稳定而临床症状较轻,可出现临床症状与影像学表现分离现象。结论肺泡蛋白沉积症具有上述典型的影像学特征,结合临床不难做出正确诊断。
Objective To investigate the imaging features and diagnostic methods of pulmonary alveolar proteinosis (PAP). Methods Thirty-seven patients with primary pulmonary alveolar proteinosis confirmed by bronchofibroscopy or thoracic biopsy and bronchoalveolar lavage were retrospectively analyzed. Results PAP chest images showed a variety of performance can be summarized as the performance of the map, gravel road-like manifestations of lung consolidation (bronchial inflatable sign) and interstitial fibrosis-like performance. Heavy lung shadow and relatively stable clinical symptoms, there may be clinical symptoms and imaging findings of separation. Conclusion Pulmonary alveolar proteinosis has the typical imaging features described above, it is not difficult to make a correct diagnosis in combination with clinical practice.
