摘　　要：目的探讨肺瘢痕癌的动态影像表现。方法对14例肺瘢痕癌的系列胸部X线和CT表现进行了回顾性分析;13例肺癌经病理或/和细胞学检查证实:腺癌12例,鳞癌1例;1例有典型的临床和影像表现。结果 13例肺结核瘢痕影像表现为多形性纤维化增殖病变和斑点片状钙化混存,均分布于上肺尖后段,1例由右中叶炎性瘢痕所致;14例肺瘢痕癌均为周围型,检出时表现为单一的结节或肿块;CT检出前的早期癌灶多表现为肺瘢痕区出现浅淡斑片状或结节样影,边缘模糊;CT扫描追踪呈现出"生长性结节"改变。结论肺瘢痕组织与后发肺癌存在着解剖关联。了解这种肺癌的动态影像表现,定期进行CT追踪,对比前后的影像资料,对早期检出肺瘢痕癌甚为重要。Objective To investigate the dynamic imaging findings of lung scar cancer. Methods The chest radiographs and CT scans of 14 cases with lung scar cancer were reviewed retrospectively. Thirteen cases lung cancer were proved by pathology and for cytology： 12 cases with adenocarcinoma, 1 case with squamous cell carcinoma; 1 cases had typical clinical and imaging features. Results The imaging findings of ohl pulmonary TB lesion in 13 cas- es mainly showed multiple morphologic fiblous and patchy or point like calcification foci,namely fibrous scar,all of them distributed in the upper lung lobe. 14 tumors were all peripheral type, which showed as single nodule or mass at the time of detection by CT scan. The cancer foci before CT detection usually manifested a patchy infiltration originat- ed from lung scar lesion, and the follow-up of chest CT scan showed ＂growing nodule＂ change. Conclusion The analomic relation between the lung scar lesion and subsequent develop lung cancer is presence. It is important to early detect this lung cancer and to recognize the dynamic imaging features of this cancer foci and to fnllow-up the chest CT scan on time, to compare with each other on those imaging findings.
