摘要
目的:探讨急性外源性变应性肺泡炎(EAA)的临床和CT特征,提高对EAA的认识。方法:回顾性分析9例急性EAA患者的临床资料及肺部CT表现。结果:5例EAA表现为典型的弥漫分布的小叶中心性浅淡结节,4例以磨玻璃样密度影为主呈地图样分布。临床7例有过敏原接触或吸入的高度提示。结论:急性EAA有典型的CT表现和临床病史,准确认识是诊断关键。
Objective：To study the clinical manifestations and CT features of acute exogenetic allergic alvolitis and to improve the understanding of this entity.Methods：Nine documented cases with acute EAA were retrospectively reviewed on interpretation of their clinical manifestations and pulmonary CT features.Results：The typical diffuse centrilobular nodules were seen in 5 patients.The ground-glass opacities with geographic distribution were seen in the other 4 patients.Antigen inhalation was suggestive in 7 patients.Conclusion：Acute EAA has typical CT findings and history of antigen inhalation.Accurate understanding would be the key for correct diagnosis.
