摘　　要：目的:通过对32例肺部炎性假瘤患者CT征象回顾性分析,着重探讨其特征性改变及鉴别诊断意义。方法:收集并分析1993～2005年期间32例炎性假瘤患者的临床资料及胸部CT扫描。结果:根据病灶特点,可分为圆形/类圆形(23/32)和不规则形(9/32)两种基本类型;病灶显示多种CT形态学表现,包括浅分叶征、“桃尖征”、“平直征”和钙化等。结论:肺部炎性假瘤具有多种CT表现,致其难以与其他肺部疾患(尤其是支气管肺癌)鉴别。但仍然存在部分征象,具有一定特异性。Objective：To study CT features of 32 cases of pulmonary inflammatory pseudotumor （PIP） retrospectively and assess their value in differentiatial diagnosis. Methods：CT findings of 32 cases of PIP were collected during 1993 to 2005 and were analyzed retrospectively. Results： The lesions were classified into two basic types according to their shape： round/round-like （23/32） and irregular （9/32）. CT features included shallow-lobulation sign,＂peach-tip＂ sign, ＂straightness＂ sign and calcification,etc. Conclusion：PIP exhibits variable features on CT which tend to be hardly differentiated from other pulmonary diseases, especially bronchiogenic carcinoma,but some of the features are helpful to the diagnosis of PIP.
