肺炎性假瘤24例的临床X线误诊分析

目的探讨肺炎性假瘤的临床与X线误诊原因；方法依据临床与X线资料分析；结果均有不同程度的呼吸道症状，有14例痰中带血丝。肿块直径小于4cm11例，密度高而均匀，边缘光整，误诊为肺良性肿瘤。肿块直径大于4cm13例，密度不太均，边缘有分叶或有毛刺，误诊为肺癌；结论临床上多无急慢性感染症状，本病与其他占位性病变极相似，缺少特征，对本病缺乏认识是导致误诊的主要原因。肿块邻近胸膜，边缘出现尖角征，动态变化缓慢这3点对提高正确诊断率有独特的价值。

Analysis of Disdiagnosis of Clinical and X-ray Features to 24 Patients with Pulmonary Inflammatony Pseudotumor

Objective To evaluate the disdiagnstic causes of clinical and X-ray features in inflammatory pseudotumor. Methods Analysing the data of clincal and X-ray features. Results All patients were accompanied with respiratory tracts' symptoms in various degrees.Blood tinged sputum was found in 14 patients. 11 patients(with tumor diameter <4cm, the density of tumor was increasing and homogeneous,the margin of tumor was smooth)were disdiagnosed as benign tumor of lung; 13 patients(with tumor diameter>4cm,the density of tumor was unhomogeneous and the tumor's margin shored 20 bulation and spicule) were disdiagnosed as cancer of lung. Conclusion Most patients were not accompanied with acute or chronic infective symptoms The inflammatory pseudotumor of lung was short of its own distinguishing features and was similar to other tumors. 3 factors to improve diagnostic accordan cerate: first, the inflammatory pseudotumor of lung is always near the pleura; second, its margin is always accompanied with sign of tip corner; third, its character changes slowly.
