肺炎性假瘤是一种少见病,常易误诊为肺癌、肺结核瘤等其它疾病。本文报告6例肺炎性假瘤,探讨其特点有:①该病多发生于女性,20至40岁之间。②病史长,病情发展缓慢,大部分病人可追溯到呼吸道感染病史。③部分病人查血有白细胞总数或单项增高趋势,符合该病为慢性炎症局灶化之学说。④用抗生素可减轻症状,肿块或许缩小,但不能完全吸收。⑤胸片:病灶阴影多为圆形,密度均匀,边缘光滑,追踪观察病灶倍 Pneumonic pseudotumor is a rare disease, often misdiagnosed as lung cancer, tuberculoma and other diseases. This article reports six cases of pneumonic pseudotumor. The characteristics of the study are: 1 The disease occurs mostly in women, between the ages of 20 and 40. 2 The medical history is long and the condition is slow. Most patients can be traced back to the history of respiratory infection. 3 Some patients had blood leukocyte counts or single-increased trend, consistent with the disease as the doctrine of chronic inflammation. 4 The use of antibiotics can reduce the symptoms and the size of the lumps may be reduced, but it cannot be completely absorbed. 5 Chest radiograph: The lesions are mostly round in shape, with uniform density, smooth edges, and follow-up observation of the lesions.
