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(P<0.05)。胸腺瘤CT分期与病理分期比较差异无统计学意义(P>0.05);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。
Objective To explore thymoma CT imaging features and its relationship with pathology. Methods Arestrospective analysis of CT imaging and clinicopathological data was carried out in 64 patients with thymoma treated in our hospital from January 2014 to January 2016,thymoma CT features were observed, relationship between CT, pathological type and stage were analyzed. Results CT features： plain scan showed that thymoma lesions existed in mediastinum anterius part, irregular shapes accounted for 79.69%, uneven densities accounted for 68.75%, enhancement scanning showed obvious enhancement existed in 46 cases, pleural invasion existed in 25 cases, pulmonary nodule existed in 5 cases, mediastinal lymph node enlargement existed in 5 cases. There was a significant difference in tumor shape, edge, density, strengthening degree, local invasion and metastasis of benign （type A and type AB） and malignant （type B and type C） thymomas （P〈0.05）. There was no significant difference in thymoma CT staging and pathological staging （P〉0.05）, there were 24 cases of type A, type AB in CT stage Ⅰ-Ⅱ stage, 27 cases of type B, type C in Ⅲ-Ⅳ stage. Condtaffon There is a significant difference in pathological type A, type AB and type B, type C thymoma CT features,CT imaging features has great value in thymoma benign and malignant （pathological type） and clinical staging judgement, can provide an important basis for clinical diagnosis and prognosis evaluation of thymoma.
