Computed tomography of five cases of thymic carcinoma was reviewed. The subtypes of thymic carcinoma were squamous (two cases), lymphoepithelioma-like (one case), undifferentiated (one case), and basaloid (one case). The patients ranged from 52 to 72 years of age. Computed tomography showed anterior mediastinal tumors infiltrating along the pleura or mediastinum with frequent internal necrosis or calcifications. The three nonsquamous cell cases developed extrathymic metastases to the mediastinal lymph nodes, lung, or chest wall. Although the CT features of thymic carcinomas were similar to those of invasive thymoma, the former showed more aggressive behavior. Among the four variants of thymic carcinoma, squamous carcinomas were less aggressive and had less tendency to develop necrosis than the others.
回顾了5例胸腺癌的计算机断层扫描结果。胸腺癌的亚型包括鳞状(2例)、淋巴上皮瘤样(1例)、未分化(1例)和基底样(1例)。患者年龄在52至72岁之间。计算机断层扫描显示前纵隔肿瘤沿胸膜或纵隔浸润,常伴有内部坏死或钙化。3例非鳞状细胞病例发生了胸腺外转移至纵隔淋巴结、肺或胸壁。尽管胸腺癌的CT特征与侵袭性胸腺瘤相似,但前者表现出更具侵袭性的行为。在胸腺癌的四种变体中,鳞状癌的侵袭性较小,发生坏死的倾向也比其他变体小。
