肺肿瘤样病变47例临床特点及误诊分析

The clinical characteristics and misdiagnosis analysis about 47 cases of lung tumor-like lesions

目的探讨肺肿瘤样病变的临床及影像学特征。方法对47例经手术及经皮肺穿刺后病理确诊肺肿瘤样病变患者临床资料进行回顾分析。结果肺肿瘤样病变在临床及影像学上均无明显的特征。术前诊断:误诊28例(59.6%),未定性11例(23.4%),诊断正确8例(17.0%)。结论对边缘清楚无分叶毛刺,纵膈淋巴结无肿大的肺部阴影也应考虑肿瘤样病变可能,肿瘤样病变临床及影像学无明显的特征,是其误诊率极高的原因。

Objective To further understanding lung tumor-like lesions through studying the clinical and radiological characteristics, Methods The clinical data composed of 47 patients who suffered from lung tumor-like lesions and who were diagnosed by surgical operation or CT-guide percutaneous biopsy were retrospectively analyzed. Results The tumor-like lesions had no obvious characteristics in both clinic and radiology examinations, Diagnosing before operating indicated erroneous diagnosis of 28 cases （59.6% ）, undecided of 11 cases （23.4 %）, and right diagnosis of 8 cases （17.0 %）. Conclusion It should be noted that the possibility of lung tumor-like lesions as existed in the cases of the lung shadow with clear edge and without stinger enlarged mediastinal lymp node, There is no obvious clinical and radiological characteristics that may lead to high rate of erroneous diagnosis.
