【摘要】：目的分析肺磨玻璃结节的CT诊断与鉴别。方法选取我院2013年5月~2016年5月收治的肺部病变患者23例作为研究对象,对其资料进行整理和分析,主要是通过分析其磨玻璃密度阴影的分布范围、边界情况,还有其他伴随症状的表现。同时通过经肺穿刺活检、经气管镜和实验室检查,分别确诊有9例和7例,余下的7例通过手术确诊。结果伴有间质病变征象例患者,表现为磨玻璃密度阴影主要是外周分布,且边界多清楚的良性病变共有10例;而边界呈毛糙状,磨玻璃密度结节多为限局性分布为癌前病变的共有6例;而常表现为磨玻璃结节在外周分布的,以实性成分为主,该还伴有支气管截断和胸膜凹陷的为恶性肿瘤共有7例。结论从对肺磨璃结节的CT观察来看,肺磨璃结节可能代表着恶性肿瘤,比如,腺癌、肺泡癌。而良性病变大部分体现为间质纤维灶;逐渐变为不典型腺瘤样增生即是癌前病变。所以对肺部磨玻璃结节早期发现及正确诊断与早期肺癌进行正确处理有着重要的临床医学意义,制定正确的治疗方案,帮助患者早日恢复健康,值得探究。
[Abstract]:Objective to analyze the CT diagnosis and differential diagnosis of milled glass nodules of the lung. Methods from May 2013 to May 2016, 23 patients with pulmonary lesions were selected as study objects, and their data were analyzed, mainly by analyzing the distribution range and boundary of density shadow of ground glass. There are other accompanying symptoms. At the same time, 9 cases and 7 cases were confirmed by lung biopsy, tracheoscopy and laboratory examination, respectively. The remaining 7 cases were diagnosed by operation. Results in the patients with interstitial lesions, the density shadow of ground glass was mainly distributed around the periphery, and there were 10 cases of benign lesions with well-defined boundary. There were 6 cases of precancerous lesion with rough boundary and limited distribution of ground glass density nodules. There were 7 cases of malignant tumor with bronchial truncation and pleural depression. Conclusion from the CT observation of pulmonary opacity nodules, they may represent malignant tumors, such as adenocarcinoma and alveolar carcinoma. Most of benign lesions are interstitial fibrous lesions, and gradually become atypical adenomatous hyperplasia is precancerous lesions. Therefore, it is of great clinical significance to find and correctly diagnose and treat the early lung cancer. It is worth exploring to establish the correct treatment plan and to help the patients recover their health as soon as possible.
