摘要
目的：评估 ＣＴ诊断良恶性胸腺瘤的价值。材料和方法：分析 ３１例经外科和病理证实的胸腺瘤的 ＣＴ表现。结果：良性胸腺瘤１０例，除１例与左肺动脉局部有粘连外，其余边界均清晰。侵袭性胸腺瘤１２例，胸腺癌９例，除１例鳞癌外，ＣＴ均为不规则肿块，血管间隙均受侵，前者心包受侵８例，胸膜受侵７例，后者心包受侵５例，胸膜受侵５例，肺转移４例，双肾上腺转移１例，胸骨破坏１例。结论。ＣＴ能准确鉴别良性恶性胸腺瘤，显示恶性胸腺瘤的浸润范围，并对侵袭性胸腺瘤和胸腺癌进行鉴别。
Purpose: To evaluate the CT manifestations of benign and malignant thymomas. Materials and Methods: The CT apperances of 31 cases of thymomas confirmed by surgery and pathology were analysed. Results: There were 10 benign thymomas. All CT scans demonstrated the soft tissue mass with clear margin except one adhered to left pulmonary artery. Of 12 invasive thymomas and 9 thymic carcinomas, all CT scans demonstrated irregular masses, but one squamous carcinoma. Cardiovascular structures were all involved. Peri cardium was involved in 8, pleural invasion in 7 of invasive thymomas. Pericardium was involved in 5, pleural invasion in 5, lung in 4, metastase to both adrenals in 1, and sternum destruction in 1 of thymic carcinoma. Conclusion: CT can deferentiate benign from malignant thymomas, also demonstrate the extent of malignant thymomas, and distinguish invasive thymomas from thymic carcinomas.
