摘要
目的分析前纵隔原发性精原细胞瘤及淋巴瘤的CT征象,以提高CT对二者的诊断准确率。方法搜集经组织病理学证实为前纵隔原发精原细胞瘤及淋巴瘤患者共50例,其中精原细胞瘤14例,淋巴瘤36例,分析两种肿瘤CT征象(位置、形态、肿块-心脏大血管界面、肿块-肺界面、坏死/囊变、钙化、肿大淋巴结、心包/胸腔积液及邻近静脉受侵情况)间的差异。结果14例前纵隔原发性精原细胞瘤表现为偏侧生长者11例,肿块内坏死/囊变者12例,其中呈弥漫分布者11例,边界模糊者11例,肿块-肺界面征阳性者10例,肿块内见钙化者5例,邻近静脉受侵者7例,合并心包/胸腔积液者4例,有肿大淋巴结者4例;36例前纵隔淋巴瘤CT表现为两侧生长者25例,肿块内坏死/囊变者19例,其中局灶性分布者11例,边缘清晰者16例,肿块-肺界面征阴性者28例,肿块内钙化者仅1例,邻近静脉无受侵者16例,有心包/胸腔积液者25例,有肿大淋巴结者25例;上述征象的差异均具有统计学意义。二者形态均多为不规则形,分别占10例、24例,肿块-心脏大血管界面征均以阳性为主,分别占13例、32例,其差异均无统计学意义。结论前纵隔原发性精原细胞瘤及淋巴瘤的CT征象具有一定特征性,有助于二者的诊断及鉴别诊断。
Objective To analyze CT features of primary seminoma and lymphoma of anterior mediastinum and improve the diagnostic accuracy of CT for such tumors.Methods 50 patients with histopathologically proven primary seminoma and lymphoma of anterior mediastinum from March 2012 to August 2018 were enrolled.All tumors were divided into seminoma group(14 cases)and lymphoma group(36 cases).The differences of CT features between the two groups were analyzed retrospectively,including location,shape,mass-cardiovascular interface(MCI),mass-pulmonary interface(MPI),necrosis,calcification,lymphadenovarix,pericardial/pleural effusion and adjacent vein invasion.Results The primary seminoma of anterior mediastinum protruded to the side of the mediastinum in 11 cases,necrosis in 12 cases,including 11 cases with scattered distribution and 11 cases with hazy boundary;MPI with irregular shape was seen in 10 cases,calcification in 5 cases,adjacent vein invasion in 7 cases,pericardial/pleural effusion in 5 cases and lymphadenovarix in 5 cases.The lymphoma of anterior mediastinum protruded to both side of mediastinum in 25 cases,had necrosis in 19 cases,including 11 cases with regional distribution and 16 cases with clear boundary,MPI with smooth shape in 28 cases,calcification in only one case,no adjacent vein invasion in 16 cases,pericardial/pleural effusion in 25 cases,lymphadenovarix in 25 cases.All those differences mentioned above between primary seminoma and lymphomas of the anterior mediastinum were statistically significant.The morphology of seminoma and lymphoma was mostly irregular(10cases and 24 cases),and MCI signs were mostly positive(13cases and 32cases).The differences mentioned above between seminoma and lymphomas were not statistically significant.Conclusion CT features of primary seminoma and lymphoma of the anterior mediastinum are characteristic,which is helpful for their diagnosis and differential diagnosis.
