摘　　要：目的：分析肺炎性假瘤的CT表现,以便与周围型肺癌及结核球等球形病灶鉴别。方法：收集11例经病理证实的肺炎性假瘤的CT及临床资料进行回顾分析。结果：病灶多位于肺边缘部胸膜下,多呈圆形或类圆形,边缘模糊,直径2～4cm,密度均匀,边缘可见粗长毛刺、尖角状突起,可有纵隔淋巴结肿大。结论：全面分析肺炎性假瘤的CT表现,重视肺部感染史,对本病的诊断和鉴别诊断很有帮助。Objective：To explore CT features and differentiation of pulmonary pseudotumor. Methods：Retrospectively studied CT findings of the 11 cases with pulmonary inflammatory pseudotumor,which were proved pathologically after surgery. Results：The main CT findings were as follows： the lesions were usually located at the periphery, most of them were round or round-like mass, margin was vague,density was dishomogeneus, diameter was 2～ 4cm. The base of the lesion were extensively adhesive to pleural with localized pleural thickening, but usually with no pleural effusion. The edge of lesion presented long and thick speculations,or shallow lobulation. Pulmonary inflammatory pseudotumor usually couldn＇t cause mediastinal lymphadenopathy, Conclusion：It is helpful to diagnosis and differentiation of pulmonary inflammatory pseudotu- mor by analyzing CT features thoroughly and to emphasize on the history of the patient.
