【摘要】：目的探讨胸腺瘤CT表现及其与病理的关系。方法对本院2014年1月-2016年1月就诊64例胸腺瘤患者CT影像学及临床病理资料进行回顾性分析,观察胸腺瘤CT表现,并分析CT与病理分型、分期的关系。结果 CT表现:平扫显示胸腺瘤病灶均在前纵隔部位;不规则形态占79.69%;密度不均占68.75%;增强扫描显示明显强化46例;胸膜侵犯25例,肺结节、纵隔淋巴结肿大各5例。良性(A型与AB型)、恶性(B型与C型)胸腺瘤在肿块形态、边缘、密度、强化程度、局部侵犯及转移方面差异显著(P0.05)。胸腺瘤CT分期与病理分期比较差异无统计学意义(P0.05);CT分期I-II期中A型、AB型24例,III-IV期中B型、C型27例。结论病理A型、AB型与B型、C型胸腺瘤CT表现存在较大的差异,CT影像学表现对胸腺瘤良恶性(病理分型)及临床分期判断有重大价值,能为胸腺瘤临床诊治、预后评估提供重要依据。
[Abstract]:Objective to investigate the pathology of thymoma and its relationship with CT. Methods in our hospital from January 2014 -2016 year in January 64 cases of patients with thymoma CT imaging and clinical pathological data were retrospectively analyzed. The observation and analysis of CT features of thymoma, CT and pathological type, stage. Results CT: scan showed that lesions were in thymoma anterior mediastinal position; the irregular shape accounted for 79.69%; uneven density accounted for 68.75%; the enhanced scan showed obvious enhancement in 46 cases; 25 cases of pleural invasion, pulmonary nodules, mediastinal lymph nodes in 5 cases. Benign (A and AB) and malignant (B and C) in the tumor shape edge of thymoma. The density, degree of enhancement, the difference of local invasion and metastasis significantly (P0.05). No statistical significance of thymoma CT staging and pathological staging difference (P0.05); A type CT stage I-II, 24 cases of type AB, B type III-IV, type C in 27 cases. Conclusion the pathological type A, type AB and B type, type C CT findings of thymoma are quite different. CT imaging is of great value in judging benign and malignant thymoma (pathological classification) and clinical stage. It can provide important evidence for clinical diagnosis and prognosis evaluation of thymoma.
