摘    要:目的:分析肺内孤立性结节的CT直接征象和间接征象并与病理结果对照,从而评价研究各种SPN直接和间接CT征象在鉴别其良恶性中的作用,提高该病例的诊断正确率。方法:回顾性分析43例肺内孤立球形结节之CT直接与间接征象,与病理结果进行对照研究。结果:下列征象对恶性病变鉴别有帮助:“空泡征”、“堆积石征”、细而深切迹、硬性细短毛刺及厚壁空洞、偏心性钙化、胸膜凹陷征、病灶远端局限性气肿改变;而病灶边缘宽浅切迹、较软性粗长毛刺、薄壁空洞、SPN内脂肪、均匀致密的钙化、病灶远端无局限性气肿改变较支持良性SPN。结论:SPN之CT征象多种多样,在判断其良恶性时应综合其各种直接和间接征象。

Abstract:Objective:To evaluate the CT direct and indirect features of solitary pulmonary nodule(SPN),and to compare with the pathological findings,so as to assess the value of identified the benign or malignant of multifarious direct or indirect features of SPN in order to improve the diagnostic accuracy.Method:The CT direct and indirect appearances were analyzed retrospectively in forty-three patients with pathologically proven SPN.Result:The following CT sign were inclined to diagnose of malignant tumor:vacuole sign,pile stone sign,the thin and deep mark,the thin and short forcedly burr and thick margin hole,the eccentricity calcify,the sunken sign of the pleura,the emphysema sign beside the nodule’s end.It abetted the benign diagnoses.For example the retuse modes,the thick and long softly burr,the flimsy margin hole,the sign of the fattiness in the focuse,the calcify was equality and compact.Conclusion:The CT direct and indirect features of solitary pulmonary nodule(SPN)are various.It should be considered in identifying the benign or malignant focus.
