目的:探讨嗜酸细胞性肺炎的X 线胸片与CT 表现及其服用皮质激素后的变化特征。材料和方法:我院临床证实的嗜酸细胞性肺炎26 例,( 男8 例,女18 例。年龄14 ～61 岁,平均43 岁) 总结其X 线胸片、CT 的影像学表现。结果:胸片与CT 表现为广泛的肺实质或肺间质浸润。病灶形态可分斑片状,结节粟粒状、网条状及兼有磨玻璃状改变。多集中于肺外围。查周围血嗜酸细胞多数增高或痰中常可找到密集的嗜酸细胞。结论:胸片、CT 表现与服用皮质激素后的变化颇具特征,可作为诊断依据。
Objective: To investigate the X-ray and CT findings of eosinophilic pneumonia and its changes after corticosteroid administration. Materials and Methods: 26 cases of eosinophilic pneumonia clinically confirmed in our hospital (8 males and 18 females, aged 14-61 years, average 43 years old) were summarized radiographs of X-ray and CT. Results: Chest radiographs and CT showed extensive pulmonary parenchyma or interstitial infiltrates. Focal morphology lesions can be patchy, nodular miliary, net-like and both ground-glass changes. More focus on the lung periphery. Check the majority of peripheral blood eosinophils or sputum can often find dense eosinophils. Conclusion: The changes of chest radiography, CT findings and corticosteroids are quite characteristic and can be used as the basis of diagnosis.
