Abstract： 目的分析亚急性或慢性过敏性肺泡炎高分辨率CT(HRCT)的影像特征,以期进一步提高其HRCT诊断的准确性. 方法 21例亚急性或慢性过敏性肺泡炎患者行肺功能、支气管肺泡灌洗、经支气管镜肺活检、胸部X线平片和HRCT. 结果 HRCT图像上16例表现出数量不等的边界模糊的小叶中心结节,13例可见磨玻璃样密度,4例有密度减低区,5例显示局限性的空气残留(air-trapping)并形成"马赛克"样灌注,2例出现散在的小叶中心性气肿、2例发生肺纤维化.结论 HRCT可以清晰显示过敏性肺泡炎病变的类型及分布.HRCT图像上表现为弥漫性边界模糊的小叶中心性结节或小叶中心结节与磨玻璃样密度及密度减低区同时存在时,应考虑亚急性或慢性过敏性肺泡炎的诊断.
