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％)；周围型肺癌多呈结节状，主要表现分叶征(56.3％)、毛刺征(40.6％)、血管集束征(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。

[Objective] To study the CT findings of pulmonary inflammatory pseudotumor and peripheral lung cancer,and make identification between them.[Methods] CT data of 11 patients with pulmonary inflammatory pseudotumor and 32 patients with peripheral lung cancer confirmed by operation and pathology were analyzed retrospectively.[Results] Most pulmonary inflammatory pseudotumor were round and located in surrounding lung or under pleural.Powder nodule sign(36.4%),peach tapering sharp sign(36.4%) and ping recti evenness sign(27.3%) could be seen in pulmonary inflammatory pseudotumor.Mediastinal lymph node metastasis(9.1%) was seldom seen in pulmonary inflammatory pseudotumor.Sentus sign(40.6%),pleural indentation sign(46.9%),bronchi and vessel cluster sign(50.0%),and mediastinal lymph node metastasis(50.0%) were often found in peripheral lung cancer.[Conclusion] According to the CT appearances of pulmonary inflammatory pseudotumor and peripheral lung cancer,we can make differential diagnosis and improve diagnostic accuracy for pulmonary inflammatory pseudotumor.
