目的:分析胸部CT毛玻璃样结节和早期肺腺癌两者之间的关系,为早期肺腺癌的诊察提供参考依据。方法:通过选取2016年1月-2016年12月在我院经过薄层低剂量胸部CT,选取35例病例,肺部毛玻璃样改变(GGO),在不同肺叶或肺段甚至肺亚段,根据不同GGO的密度、大小、形态、血管征、支气管充气征、胸膜凹陷包括纯的pGGO和部分实性混合型mGGO及完全实性结节与小于等于3cm的肿块比较。结果:在35例的GGO患者中,其中30例在LDCT上表现为肺周围区圆形GGO,其中15例病灶内不含有实性成分,而10例病灶内含有实性成分,5例病灶内有不含有实性成分以及含有实性成分两种GGO。其余的5例在LDCT中检查结果不显示为GGO。含有不同密度的实性成分的比例分为纯的GGO就是pGGO、部分实性psGGO和实性结节SN在恶性病变中分别占18%,63%,7%。结论:胸部分GGO毛玻璃样结节是与早期肺腺癌之间的关系是息息相关的,对于早期的肺腺癌发现及及时的诊疗有非常重要的意义。
OBJECTIVE: To analyze the relationship between breast CT fringe-like nodules and early lung adenocarcinoma and to provide a reference for the early diagnosis of lung adenocarcinoma. Methods: From January 2016 to December 2016, we selected 35 cases, thin glass-like changes (GGO) in different lung lobes or lung segments and even lung sub-segments through thin-layer, low-dose chest CT in our hospital. Different GGO density, size, morphology, vascular sign, bronchial airway sign, pleural indentation including pure pGGO and partial real mixed mGGO and complete solid nodules compared with less than 3cm mass. Results: Of the 35 GGO patients, 30 of them showed circular GGO in the peripheral region of the lung on LDCT. Among them, 15 had no real component in the lesions, while 10 had lesions in the lesions and 5 in the lesions There are two kinds of GGO that do not contain solid ingredients and contain solid ingredients. The remaining 5 cases did not show GGO in LDCT. The proportion of solid with different densities is divided into pure GGO is pGGO, partial real psGGO and solid nodules SN in malignant lesions accounted for 18%, 63%, 7%. Conclusion: GGO in the thoracic area is closely related to early lung adenocarcinoma. It is very important for the early detection and timely diagnosis and treatment of lung adenocarcinoma.
