摘　　要：目的探讨胸腺鳞癌的CT影像特征.方法回顾性分析经病理证实的19例胸腺鳞癌临床资料和CT图像.所有病例均行CT平扫+双期增强扫描.结果19例胸腺鳞癌均为单发不规则肿块,最大径平均(5.5±1.6)cm,可见坏死灶(84%)、钙化灶(32%)以及局部边缘不清(84%)等征象.增强扫描病灶均呈渐进性强化,大部分为中度强化(84%).邻近结构常见受累,如病灶周围脂肪絮状影(100%)、大血管受侵(79%)、心包受侵(74%)、瘤肺界面不规则膨隆(79%)以及纵隔淋巴结增多或肿大(100%).结论胸腺鳞癌的CT影像特征多为单发不规则肿块,易坏死、钙化,局部边缘模糊,增强扫描呈渐进性强化,常累及纵隔脂肪、大血管以及心包等邻近结构,并伴有纵隔淋巴结增多或肿大.Objective To investigate the CT features of thymic squamous cell carcinoma.Methods The clinical data and CT images of 19 patients with thymic squamous cell carcinoma confirmed by pathology were analyzed retrospectively.All patients underwent CT plain scan and dual-phase contrast-enhanced scan.Results All of the 19 cases showed as a single irregular mass,the average maximum diameter was(5.5±1.6)cm,with signs of necrosis(84%),calcifications(32%),and blurred local margin(84%).All the lesions were progressive enhancement in the contrast-enhanced scan,and most of them showed moderate enhancement(84%).Adjacent structures were commonly involved,such as fat flocculent shadow around the lesion(100%),macrovascular invasion(79%),pericardial invasion(74%),irregular bulge of the tumor-lung interface(79%),and increased or enlarged mediastinal lymph nodes(100%).Conclusion CT features of thymic squamous cell carcinoma are mostly single irregular mass with necrosis,calcification,blurred local margin,and progressive enhancement on contrast-enhanced scan.Mediastinal fat,large vessels,pericardium and other adjacent structures are often involved,accompanied by increased or enlarged mediastinal lymph nodes.
