【摘要】：目的:评价低危、高危胸腺瘤及胸腺癌CT特征,为术前诊断及预后评价提供依据。方法:回顾分析经手术及病理证实的59例低危、高危胸腺瘤及胸腺癌的CT表现,并比较各组病灶差异。结果:胸腺癌较低危胸腺瘤更常见坏死及囊变、不规则、分叶、灌注式生长及肺侵犯。胸腺癌较低危胸腺瘤及高危胸腺瘤更常表现为不均匀强化、边缘毛糙不清、更长径、心包侵犯、大血管侵犯、心包积液、淋巴结肿大及患者年龄更大;更少见表现为类圆形的形态。低危胸腺瘤较高危胸腺瘤及胸腺癌强化幅度更高、胸膜侵犯更少且更少临床症状。结论:胸腺癌、高危胸腺瘤、低危胸腺瘤3组间的多层CT扫描表现有明显差异,有助于鉴别诊断。
[Abstract]:Objective: to evaluate CT features of low risk, high risk thymoma and thymic carcinoma, and to provide basis for preoperative diagnosis and prognosis evaluation. Methods: Ct findings of 59 cases of low-risk, high-risk thymoma and thymic carcinoma confirmed by surgery and pathology were analyzed retrospectively and the difference of the lesions in each group was compared. Results: necrosis and cysts, irregular lobulation, perfusion growth and lung invasion were more common in thymic carcinoma than in low risk thymoma. Thymic carcinoma is more often characterized by uneven enhancement, rougher edges, longer diameter, pericardial invasion, large blood vessel invasion, pericardial effusion, enlarged lymph nodes and older patients than low risk thymoma and high risk thymoma. It is more rare to show a round shape. Low risk thymoma had higher enhancement and less pleural invasion than high risk thymoma and thymic carcinoma. Conclusion: the multislice CT findings of thymic carcinoma, high risk thymoma and low risk thymoma are significantly different among the three groups, which is helpful for differential diagnosis.
