对21例术前诊断或疑为肺癌，术后证实为炎性假瘤的病例进行分析．显示肺癌与炎性假瘤在病史、X线胸片及CT表现上有许多相似之处。认为若经短期诊断性治疗（＜4周）无效，或肿块直径＞3．5cm、CT值超过32Hu，应尽早手术。术中应冰冻切片检查。

Show lung cancer and inflammatory pseudotumor in history, X-ray and CT findings have many similarities. If short-term diagnostic treatment (<4 weeks) is invalid, or tumor diameter> 3.5cm, CT value of more than 32Hu, surgery should be as soon as possible. Intraoperative frozen section should be checked.
