肺部31例炎性肿块的CT诊断分析

31 Cases of Pulmonary Inflammatory Mass CT Diagnostic Analysis

目的对肺部肿块型炎性病变cT征象进一步认识、分析，提高cT对该病的正确诊断率。方法选取并分析31例经手术病理及临床随访证实的肺部炎性肿块的cT狂象。结果31例肺炎性肿块中，30例病灶为单发，1例为多发病灶；两肺下叶基底段15例，背段6例，上叶后段（尖后段）4例，中叶（舌段）6例；29例病灶位于胸膜下，16例广基底与胸膜相连；病灶边缘光整呈类圆形23例，边缘形态不规则、有粗长毛刺或锯齿状8例，呈桃尖征5例，病灶周围晕征17例，细支气管充气征4例；病灶边缘垂直于胸膜的刀切样改变7例。结论全面分析cT征象，结合其临床资料能提高肺部炎性肿块病变的正确诊断率。

Objective To analyse the lung mass type of inflammatory lesions under CT findings and improve the CT correct diagnosis rate for the disease.Method Selection and analysis of 31 cases with operation pathology and clinical follow-up confirmed pulmonary inflammatory mass CT signs.Result Of 31 cases of inflammatory mass,30 cases of the lesion were solitary,1 case multiple lesions;Two basal segment of lower lobe of lung in 15 cases,back section in 6 cases,upper lobe posterior segment （after the tip section） in 4 cases,（the middle tongue segments） in 6 cases;In 29 cases the lesion located in the subpleural.In 16 cases with pleural broad has,lesion edge finishing was round in 23 cases,edge of irregular shape,long spiculation or serrated in 8 cases,peach tip syndrome in 5 cases,lesion of the peripheral halo sign in 17 cases,fine air bronchogram in 4 cases,lesion edge perpendicular to pleura knife cutting changes in 7 cases.Conclusion Comprehensive analysis of CT features,combined with the clinical data can improve pulmonary inflammatory mass lesions diagnosis.
