误诊为周围型肺癌的肺内良性病灶37例CT表现对比及误诊分析

摘要

Objective To compare and analyze the CT findings of 37 cases of benign pulmonary lesions misdiagnosed as peripheral lung cancer,and to study their main differential points in order to enhance the accuracy of diagnosis and reducing misdiagnosis. Methods A retrospec-tive analysis is carried out in 37 cases of benign pulmonary lesions misdiagnosed as peripheral lung cancer,and to observe their characteristic fea-tures in CT scanning,then these data are compared with those of 37 cases of peripheral lung cancer diagnosed in the same period,then making a-nalysis. Results In comparison with those of control group,the proportion of lobulation sign,spicular sign and vacuolar signs are statistically sig-nificant in patients of misdiagnosed group. There is no statistical difference between those of misdiagnosed group and control group in inflatable bronchus signs and pulmonary cavity. Conclusion The imaging features may be same or similar between benign pulmonary lesions and peripheral lung cancer,hence.we should analyze the morphological features of lesions and improve cognition of imaging features in lesions,and make its diag-nosis combined with clinical records in order to reduce the possibility of misdiagnosis.%目的 对比分析37例误诊为周围型肺癌的肺内良性病灶及37例同期确诊的周围型肺癌影像学特征,了解其鉴别要点,以提高诊断正确率,减少误诊.方法 回顾性分析37例经CT检查被误诊为周围型肺癌,后经各类途径证实的肺内良性病灶CT影像资料,观察病灶的影像学特征,并与同期确诊的周围型肺癌37例进行对比分析.结果 误诊组分叶征?毛刺征?空泡征比率均低于对照组,差异有统计学意义(P 0. 05).结论 肺内良性病灶可能具有部分与周围型肺癌相同或相似的影像学特征,在诊断中还需对病灶形态学细节进行分析,提高对病灶影像学特点的认识,并结合临床资料综合诊断,以减少误诊.
