摘　　要：目的探讨侵袭性胸腺瘤的CT表现及其临床诊断意义。方法选择经手术病理学确诊、临床资料完整的胸腺瘤患者52例为研究对象,统计21例侵袭性胸腺瘤患者的CT表现,并对比非侵袭性胸腺瘤患者的CT表现。结果 CT诊断21例侵袭性胸腺瘤患者的灵敏度为95. 0%、特异度为91. 3%、阳性预测值为90. 5%和阴性预测值为95. 5%。侵袭组与非侵袭组患者的胸腺瘤在形态、钙化、囊性变或中心坏死、纵隔脂肪线、均匀增强方面存在统计学差异(P <0. 05)。结论 CT诊断侵袭性胸腺瘤具有操作简便、诊断时间短、可靠性高等优点,且根据CT表现可以有效鉴别侵袭性胸腺瘤与非侵袭性胸腺瘤,临床实用价值较高。Objective To investigate the CT findings of invasive thymoma and its clinical significance.Methods Fifty-two patients with thymoma diagnosed with surgical pathology and complete clinical data were selected as study subjects.The CT features of 21 patients with invasive thymoma were counted and the CT findings of non-invasive thymoma patients were compared.Results The sensitivity,specificity,positive predictive value and negative predictive value of the 21 patients with invasive thymoma were 95.0%,91.3%,90.5%and 95.5%respectively.There was a statistically significant difference in morphological,calcification,cystic degeneration or central necrosis,mediastinal fat line,and even enhancement of thymoma in the invasive and non-invasive groups(P<0.05).Conclusion CT in the diagnosis of invasive thymoma with advantages of simple operation,short diagnosis time and high reliability,and according to the CT presentation can effectively identify invasive thymoma with non invasive thymoma,clinical practical value is higher.
