摘　　要：目的:探讨CT对纵隔内原发性精原细胞瘤的诊断价值。方法:搜集经病理证实的纵隔内原发性精原细胞瘤6例,总结和分析其临床及CT表现。结果:纵隔原发性精原细胞瘤好发于青壮年,临床表现无特异性。6例肿瘤均位于前中上纵隔,病变范围较大。CT表现为密度均匀3例,密度不均3例;2例边界清楚,4例可见周边浸润,1例侵及双侧胸膜和右上肺,1例累积心包,包绕主动脉及无名动静脉、上腔静脉受侵闭塞。结论:CT对纵隔原发性精原细胞瘤的密度、周围关系具有重要的诊断价值。Objective： To explore the diagnostic value of CT in primary mediastinal seminoma. Methods： The clinical and CT manifestations of 6 patients with primary mediastinal seminoma proven by histological examinations were retrospec tively analyzed. Results： Primary mediastinal seminoma usually occurred in the young adults with no specific clinical manifestations. The 6 lesions were all located in anterior-middle-superior mediastinum with a large size. Three cases had homogeneous density,and others inhomogeneity. Two cases had clear margins,and infiltrating growth was found in 4 cases. Conclusion：CT is of great diagnostic and clinical values according to the density and surroundings of primary mediastinal seminoma.
