原发纵隔内胚窦瘤的CT诊断

目的:提高对纵隔内胚窦瘤CT表现的认识。方法:回顾性分析11例经病理学证实的纵隔内胚窦瘤的临床和CT资料。结果:11例病灶CT平扫均表现为实性肿块,8例肿块表现为不均质密度,3例表现为均质密度。9例增强CT扫描表现为中-高度不均匀强化,其中5例表现为周边部的不规则线状及网状强化。结论:纵隔内胚窦瘤的CT表现虽具有恶性肿瘤的特点,但缺乏特异性,确诊有赖于病理学检查。

CT Diagnosis of Primary Mediastinal Endodermal Sinus Tumor

Purpose:To study the CT features of mediastinum endodermal sinus tumor.Methods:Eleven cases of pathological confirmed mediastinum endodermal sinus tumors were retrospectively analyzed.The CT image data and clinical materials were analyzed.Results:The lesions were shown as solid masses in all 11 cases.The density of the lesions was homogeneous in 8 cases and inhomogeneous in 3 cases.On post contrasted CT,9 cases of the tumors were mildly - heavily inhomogeneously enhanced,and 5 of them were with linear or reticular enhancement.Conclusion:The features of mediastinum endodermal sinus tumor have the characteristics of malignant tumor,but lack of specificity.The diagnosis of it depends on the pathological examination.
