摘　　要：目的:分析肺炎性假瘤CT征象。方法:收集14例经手术病理证实为肺炎性假瘤患者的CT及增强CT的影像学资料,分析肺炎性假瘤的部位、大小、密度、形态、边缘及病灶周围的影像学表现。结果:14例肺炎性假瘤病灶多位于肺外周部,均为单发;病灶边界多不清楚,其中9例病例可见病灶边缘长毛刺征;病灶密度不均,有低密度区、空洞及支气管空气征;11例伴有明显胸膜反应;11例患者增强CT示病灶边缘出现强化。结论:肺炎性假瘤的CT表现不具有特征性,必须结合临床表现对该病作出诊断。Objective： To analyze the CT signs of pulmonary inflammatory pseudotumor. Methods： The clinical data, CT images and pathological results of 14 cases of pulmonary inflammatory pseudotu- mor patients were collected to analyze the location, size, density, form, edge, MRI of lesion surround- ing of pseudotumor. Results： The lesions were located in the periphery of the lung, mainly as single shot; the edges of the lesion were unclear, 9 cases presented multiple long spiculation. The densities of the lesions were not even with low density area, multiple cavities and bronchial sign. 11 cases showed obvious pleural reaction, and 11 enhanced CT results indicated lesion edge enhancement. Conclusion ： CT features of pulmonary inflammatory pseudotumor were not characteristic, which must be diagnosed with clinical manifestation.
