【摘要】：目的:評價低危、高危胸腺瘤及胸腺癌CT特征,為術前診斷及預后評價提供依據(jù)。方法:回顧分析經(jīng)手術及病理證實的59例低危、高危胸腺瘤及胸腺癌的CT表現(xiàn),并比較各組病灶差異。結果:胸腺癌較低危胸腺瘤更常見壞死及囊變、不規(guī)則、分葉、灌注式生長及肺侵犯。胸腺癌較低危胸腺瘤及高危胸腺瘤更常表現(xiàn)為不均勻強化、邊緣毛糙不清、更長徑、心包侵犯、大血管侵犯、心包積液、淋巴結腫大及患者年齡更大;更少見表現(xiàn)為類圓形的形態(tài)。低危胸腺瘤較高危胸腺瘤及胸腺癌強化幅度更高、胸膜侵犯更少且更少臨床癥狀。結論:胸腺癌、高危胸腺瘤、低危胸腺瘤3組間的多層CT掃描表現(xiàn)有明顯差異,有助于鑒別診斷。
[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.
