【摘要】：目的:探讨MSCT对低危型、高危型胸腺瘤及胸腺癌的鉴别诊断价值。方法:将68例经穿刺或手术病理证实的胸腺上皮性肿瘤(TETs),按WHO简化病理分型分为低危型胸腺瘤、高危型胸腺瘤和胸腺癌三组,对三组的MSCT征象进行统计学分析。结果:68例TETs中,低危型胸腺瘤31例(A型4例、AB型19例、B1型8例)、高危型胸腺瘤15例(B2型9例、B3型6例)、胸腺癌22例。高危型胸腺瘤、胸腺癌均较低危型胸腺瘤更易表现为肿瘤边缘不规则或分叶(P均0.05);高危型胸腺瘤、胸腺癌均较低危型胸腺瘤更易出现对胸膜/心包、邻近大血管侵犯(P均0.05);增强后密度不均及囊变坏死率在胸腺癌和低危型胸腺瘤间均具有显著性差异(P均0.001);胸腺癌出现纵隔淋巴结转移较低危型、高危型胸腺瘤更为常见(P0.05);而瘤内钙化在三者间两两比较均无明显统计学差异(P均0.05)。结论:MSCT对WHO简化病理分型的TETs具有一定的鉴别诊断价值。
[Abstract]:Objective: to investigate the value of MSCT in the differential diagnosis of low-risk, high-risk thymoma and thymic carcinoma. Methods: 68 cases of thymic epithelial tumor confirmed by puncture or pathology were divided into low-risk thymoma according to WHO simplified pathological classification. High risk thymoma and thymic carcinoma were statistically analyzed in three groups. Results in 68 cases of TETs, the signs of Thymoma and thymic carcinoma were analyzed statistically. There were 31 cases of low risk thymoma, 4 cases of type A, 19 cases of type B 1, 15 cases of high risk type thymoma, 9 cases of type B 3 and 22 cases of thymic carcinoma. Thymic carcinomas were more prone to appear as irregular margin or lobulated thymoma than low-risk thymoma, and high risk thymoma and thymic carcinoma were more likely to appear pleural / pericardium than low-risk thymoma. There were significant differences in density and cystic necrotic rate between thymic carcinoma and low-risk thymoma after enhancement (P < 0.05), and there were significant differences between thymic carcinoma and low-risk thymoma (P < 0.001), mediastinal lymph node metastasis was lower in thymic carcinoma, mediastinal lymph node metastasis was found in thymic carcinoma. High risk thymoma is more common than P0.05A, but there is no significant difference in calcification between the three groups (P 0.05). Conclusion WHO has a certain value in differential diagnosis of TETs with simplified pathological classification.
