目的分析fGGO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fGGO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 fGGO的 MSCT特征与病灶的病理类型显著相关，值 得临床重视。

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.
