摘　　要：目的:探讨睾丸精原细胞瘤MRI诊断与鉴别诊断,以期提高对此病认识度。方法:回顾性分析2010年3月至2013年3月14例经病理组织学证实为睾丸精原细胞瘤患者,均MRI检查,观察其影像学表现,并和病理形态学进行比较。结果:所有睾丸精原细胞瘤均位于睾丸实质内,未突破白膜,其中8例结节形,4例为不规则和分叶状且边界清楚,11例表现为均匀一致低信号,2例不均匀混合信号。增强扫描中,9例病灶边缘可见有纤维分隔样早期明显强化,TIC为平台型;5例肿瘤伴出血坏死,为不均匀强化,TIC为速升缓降型。病理表现为肿瘤细胞形态一致圆形或三角形,有胞膜,浆核丰富,核分裂常见。结论:睾丸精原细胞瘤的MRI特征性表现为T2WI病灶均匀低信号影并纤维血管间隔早期强化。Objectives： To study the MRI diagnosis and differential diagnosis of testicular seminoma,in order to improve the recognition of this disease. Methods： Retrospective analysis was done on 14 patients with testicular seminoma confirmed by pathological histology from March 2010 to March 2013. Imaging findings were observed and pathological morphology was compared. Results： The testicular seminoma was in testicular and didn＇t break through albuginea,of which there were 8 cases of nodular type,4 cases of irregular and lobulated with clear border,11 cases characterized by uniform low signal and 2 cases of mixed signal. In edge enhancement scan,there were 9cases of lesions seen with obvious early sample separation for reinforcement,TIC for platform type; there were 5 cases of tumor with bleeding necrosis,uneven reinforce,TIC for speed rise slow down type. Pathology of the tumor cells formed consistent circle or triangle,with cell membrane,rich pulp nuclear and nuclear fission. Conclusion：MRI of testicular seminoma is characterized with even low signal in T2 WI lesions and early strengthen at interval vascular.
