肺泡蛋白沉积症的X线诊断与鉴别诊断

目的：探讨肺泡蛋白沉积症（ＰＡＰ）的Ｘ线诊断、Ｘ线分型与鉴别诊断。方法：回顾分析１５例经病理证实的ＰＡＰ的Ｘ线表现，全部病例都作了胸部Ｘ线平片检查，其中３例作了全肺体层。结果：１５例中９例表现为双肺广泛分布的小结节状阴影，３例表现为以肺门为中心，向外放射的蝶冀状阴影，３例表现为双下肺野大片状致密阴影。结论：ＰＡＰ根据Ｘ线表现可分为多发小结节型、类肺水肿型和类炎症型，分别应与肺泡细胞癌、肺水肿及肺部

Chest X-ray diagnoses for pulmonary alveolar proteinosis

Objective:To study X ray diagnosis,classification and differential diagnosis of pulmonary alveolar proteinosis(PAP) Methods:Chest X ray films were retrospectively analyzed in 15 patients with PAP,3 cases of them were taken lungs tomography Results:There were multiple small nodules in bilateral lungs in 9 cases Bullerfly wing like shadow was showed beside bilateral lung hili in 3 cases Great piece shadow can be found in both inferior lungs in 3 cases Conclusion:PAP can be classified to multiple small nodule type,lung edema like type and pneumonia like type They should be distinguished from pulmonary alveolar cell carcinomas,lung edema and chronic pneumonia,respectively
