1、肺部炎性假瘤与周围型肺癌的CT诊断及鉴别诊断裴林惠1王路昌1赵德明1丁建国2曾维新2(1上海市第二人民医院放射科200011；2复旦大学附属中山医院放射科200032)【摘要】目的探讨肺炎性假瘤的CT征象及与周围型肺癌的鉴别。方法回顾分析11例经手术和病理证实的肺炎性假瘤的CT征象，并与32例经手术和病理证实的周围型肺癌CT征象对照。结果肺炎性假瘤多呈圆形，位于肺外围或胸膜下，主要表现有桃尖征(36.4%)、平直征(27.3%)、晕征(54.6%)和病灶下缘散在结节征(36.4%)、纵隔淋巴结肿大少见(9.1%)；周围型肺

2、癌多呈结节状，主要表现分叶征(56.3%)、毛刺征(40.6%)、血管集朿征(50.0%)和胸膜凹陷征(46.9%),纵隔淋巴结肿大多见(50.0%)。结论多种CT征象综合有助于肺炎性假瘤与周围型肺癌的鉴别和提高肺炎性假瘤的CT诊断准确性。【关键词】肺炎性假瘤周围型肺癌x线CT诊断鉴别【中图分类号】R730.4【文献标识码】A【文章编号】2095-1752(2013)33-0128-03CTAppearancesofPulmonaryInflammatoryPseudotumorandPripheralLungCancer
