肺炎性假瘤一般认为是一种非特异性炎症所致的肿瘤样改变。其确切的发病率尚不清楚。有作者报告在肺和支气管肿瘤中炎性假瘤的发病率为0.7％。近年来本病有增多趋势。临床上常易与肺癌、肺结核以及肺内其它团块病变相混淆。因此值得引起胸外科医师的重视。 Pneumonic pseudotumor is generally considered to be a tumor-like change caused by non-specific inflammation. The exact incidence is not clear. Some authors reported an incidence of inflammatory pseudotumor of 0.7% in lung and bronchial tumors. In recent years, the disease has increased. It is often clinically confused with lung cancer, tuberculosis, and other clumps in the lung. It is therefore worthwhile to pay attention to thoracic surgeons.
