摘　　要：目的探讨胸腺上皮肿瘤的MSCT表现与WHO病理组织学分型的相关性。方法收集本院经病理证实的胸腺上皮肿瘤62例，其中51例经手术病理确诊，11例经穿刺活检确诊。回顾性分析肿瘤的CT表现及其病理分型，并依其病理分型进行重新简化分组．分为低危组（A、AB、B1型）和高危组（B2、B3、C型）进行对照研究。结果本研究低危组35例，高危组27例。MSCT征象上，肿块大血管接触面（mass cardiovascular interface，MCI）模糊或铸型、肿块肺界面（mass pulmonary interface．MPI）不规则、大血管侵犯及胸膜侵犯在高危组明显多于低危组．差异有统计学意义（所有P〈0．05），血管侵犯只见于高危组。结论MCI模糊或铸型、MPI不规则、血管侵犯、胸膜侵犯征象在鉴别高危组与低危组胸腺上皮肿瘤方面有重要价值。Objective To explore the correlation of the MSCT features and WHO histological classification of thymic epithelial tumors. Methods Sixty two patients with thymic epithelial tumors pathologically confirmed by either surgery（51 cases） or biopsy （ 11 cases） were retrospectively reviewed. According to the pathological type, all the cases were simply divided into two groups： low-risk group （types A, AB, and B1） and high-risk group （types B2, B3 and C）. Results 35 and 27 cases were low-risk tumors and high risk tumors, respectively. Incidence of MSCT findings,including casting type or irregular mass cardiovascular interface （MCI）, irregular mass pulmonary interface （MPI）, great vessel infiltration and pleural infiltration were statistically higher in high-risk group than in the other （P〈0.05）. Specifically, sign of great vessel infiltration existed only in high-risk group. Conclusion MSCT find- ings, such as casting type or irregular MCI, irregular MPI,great vessel infiltration and pleural infiltration are of indispensable value to differentiate thyrnic epithelial tumors with high-risk from those with low-risk.
