孤立性肺小结节的胸部高分辨CT诊断与病理对照分析

Comparative Analysis of High Resolution CT Diagnosis and Pathology of Solitary Pulmonary Nodules

目的:分析孤立性肺小结节(SPN)的胸部高分辨CT诊断与病理对照情况。方法:2018年7月~2019年11月接收的140例经病理确诊为孤立性肺小结节的患者,接受胸部高分辨CT扫描,对图像进行观察,对图像中结节的大小、边缘、内部等征象对照病理结果。结果:140例SPN患者经CT诊断结果显示,恶性结节有102例(72.9%),78例为腺癌,15例为鳞癌,3例为类癌,2例为腺鳞癌,2例为小细胞癌,2例为大细胞癌,结节直径(2.10±0.68)cm;良性结节有38例(27.1%),20例为炎性假瘤,9例为错构瘤,8例为结核瘤,1例为硬化性血管瘤,结节直径(1.86±0.58)cm;140例肺结节患者,左肺69例,50例为恶性,19例为良性;右肺71例,52例为恶性,19例为良性;左右分别、良恶情况对比,差异无统计学意义(P>0.05);对良性结节与恶性结节进行对比,结节分叶、胸膜凹陷、毛刺征、空泡及支气管充气征及血管集束征等情况比较,恶性组发生率更高,差异具有统计学意义(P<0.05)。结论:SPN患者经胸部高分辨CT诊断,观察肺结节边缘、内部形态,能准确鉴别结节的良恶性。

Objective:To analyze the chest high-resolution CT diagnosis of SPN and the pathological contrast.Methods:From July 2018 to November 2019,140 patients who were confirmed as solitary pulmonary nodules by pathology received chest high-resolution CT scan.The images were observed,and the size,edge,interior and other signs of the nodules in the images were compared with the pathological results.Results:The CT findings of 140 SPN patients showed that there were 102 malignant nodules(72.9%),78 adenocarcinoma,15 squamous cell carcinoma,3 carcinoid,2 adenosquamous carcinoma,2 small cell carcinoma,2 large cell carcinoma,with nodule diameter of(2.10±0.68)cm,38 benign nodules(27.1%),20 inflammatory pseudotumors,9 hamartoma,8 tuberculoma,1 sclerosing hemangioma tumor,nodule diameter(1.86±0.58)cm;140 cases of pulmonary nodule,69 cases of left lung,50 cases of malignant,19 cases of benign;71 cases of right lung,52 cases of malignant,19 cases of benign;left and right,respectively,good and bad situation comparison,no significant difference(P>0.05);benign nodule and malignant nodule comparison,nodule lobes,pleural depression,burr sign,vacuole and bronchial inflation The incidence of malignant group was higher than that of vascular cluster(P<0.05).Conclusion:The diagnosis of SPN by chest high-resolution CT and the observation of the edge and internal morphology of pulmonary nodules can accurately identify the benign and malignant nodules.
