摘　　要：目的探讨CT在胸腺上皮肿瘤WHO新分类诊断及鉴别诊断中的应用价值.方法回顾性分析经病理证实的胸腺上皮肿瘤患者40例,通过对其术前CT平扫及增强的多种CT特征及临床资料的统计分析,得出A、AB、B1、B2、B3及C型6种分型胸腺瘤的CT诊断及鉴别诊断特征.结果40例胸腺上皮肿瘤中A型6例(15%)、AB型11例(27.5%)、B1型4例(10%)、B2型7例(17.5%)、B3型4例(10%)及C型8例(20%).6种类型胸腺瘤在肿块外形、边界、囊变(坏死)、明显强化、与邻近结构关系、有无胸腔积液及淋巴结、心包、胸膜转移方面比较存在显著统计学差异(P<0.05).结论胸腺上皮肿瘤的肿块外形、边界、囊变(坏死)、强化程度、与邻近结构关系、有无胸腔积液及淋巴结、心包、胸膜转移的CT表现在WHO各分型鉴别诊断中具有重要的应用价值.Objective To investigate the application value of CT in the diagnosis and differential diagnosis of thymic epithelial tumors between WHO new classifications.Methods 40 patients with thymic epithelial tumors confirmed by pathology were analyzed retrospectively.Various clinical data and imaging features of preoperatively plain and enhancement CT were analyzed to obtain the diagnosis and differential diagnosis among 6 types of thymoma(type A,AB,B1,B2,B3,and C).Results The 40 cases of thymic epithelial tumors included 6 cases of type A(15%),11 cases of type AB(27.5%),4 cases of type B1(10%),7 cases of type B2(17.5%),4 cases of type B3(10%)and 8 cases of type C(20%).There were significant differences among these 6 types of thymoma in the tumor shape,edge,cystic change(necrosis)f enhancement degree,surrounding tissue invasion,presence or absence of pleural effusion,enlarged lymph node,and pericardial and/or pleural metastases(P<0.05).Conclusion CT has important application value in the differential diagnosis of thymic epithelial tumors with different WHO types,including some CT features such as tumor shape,edge,cystic change(necrosis).enhancement degree,surrounding tissue invasion,presence or absence of pleural effusion,enlarged lymph node,and pericardial and/or pleural metastases.
