【摘要】[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.%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
