肺局灶性磨玻璃密度结节(fGGO)的多层螺旋CT(MSCT)特征与病灶良恶性的相关性分析

目的分析f GGO的MSCT特征与病灶良恶性的相关性。方法对我院2012年4月至2015年4月收治的72例f GGO患者的临床资料进行回顾性分析。结果 72例患者中,在病灶大小方面,炎症病灶最大径均≥1cm,肺不典型腺瘤样增生AAH病灶最大径均≤1cm;在形态轮廓方面,7例炎症患者呈斑块状,AAH患者均为圆形或类圆形,细支气管肺泡癌BAC和腺癌患者主要呈分叶征、圆形等;在边缘方面,炎症患者均具有模糊的边缘,AAH患者均具有光整而清晰的边缘,BAC和腺癌中具有毛糙的边缘或伴毛刺征22例,具有光整而清晰的边缘32例;在周围改变方面,炎症患者中胸膜增厚6例,BAC和腺癌患者中胸膜凹陷30例,胸膜增厚26例。结论 f GGO的MSCT特征与病灶的病理类型显著相关,值得临床重视。

Correlation Analysis of Multi-slice Spiral CT (MSCT) Features of Focal Ground-glass Opacity (fGGO) and the Property of the Pulmonary Lesions

Objective To analyze the correlation analysis of MSCT features of fGGO and benign and malignant lesions.Methods The clinical data of 72 cases of fGGO patients treated in our hospital from April 2012 to April 2015 were analyzed retrospectively. Results Among the 72 cases of patients, in terms of size, the maximum diameter of inflammatory lesions were more than 1cm, the maximum diameter of AAH(Atypical adenomatous hyperplasia) were less than 1cm. 7 cases of inflammatory lesions were shown in spots, AAH were round or oval, BAC(bmnchioloalveolar cell carcinoma)were lobulated or round; inflammation lesions with fuzzy edges, AAH had sharp and smooth edges, BAC and adenocarcinoma had rough edges or burrs sign with 22 cases with sharp edges while finishing 32 cases; change in the surrounding areas, 6 cases of inflammation lesions with pleural thickening,30 cases of BAC and adenocarcinoma had pleural indentation, 26 cases had pleural thickening.Conclusion MSCT features of fGGO were significantly associated with pathology, and be worthy of the full attention of clinical doctors.
