【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。更多还原

【Abstract】 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:lowrisk 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 findings,such as casting type or irregular MCI,irregular MPI,great vessel infiltration and pleural infiltration are of indispensable value to differentiate thymic epithelial tumors with high-risk from those with low-risk.更多还原
