	目的：探讨不典型A型胸腺瘤的MSCT影像学特点，提高CT诊断水平。方法：回顾性分析18例经手术与病理证实为不典型A型胸腺瘤的临床资料和影像学资料。结果：18例肿块均呈软组织密度，其中位于前上纵隔16例、前中纵隔2例、伴钙化4例。增强扫描12例肿块呈轻度不均匀强化，2例肿块呈轻中度均匀强化，2例呈环形强化，13例内部可见片状低密度延迟强化区，内含粗大血管10例，伴液化坏死14例。结论：MSCT对不典型胸腺瘤的诊断有一定价值。<br />
Objective: To investigate the imaging features of atypical thymoma type A (MSCT) in order to improve CT diagnosis. Methods: The clinical and imaging data of 18 cases with atypical thymoma type A confirmed by surgery and pathology were retrospectively analyzed. Results: All the 18 cases showed soft tissue density, including 16 cases in anterior superior mediastinum, 2 cases in anterior mediastinum and 4 cases with calcification. On contrast-enhanced scan, 12 cases of mass presented mild heterogeneous enhancement, 2 cases presented mild to moderatehomogeneous enhancement, 2 cases presented circular enhancement, 13 cases showed internal patchy low-density delayed enhancement area, including 10 cases of thick vessels and 14 cases accompanied by liquefied-necrosis. Conclusion: MSCT is valuable in the diagnosis of atypical thymoma.
