摘　　要：目的探讨不同病理类型的睾丸生殖细胞肿瘤在MRI中的表现,进一步提高MRI对该疾病的诊断价值。方法回顾性分析13例经手术病理证实的睾丸生殖细胞肿瘤患者的临床及MRI资料,所有病例均行MRI平扫及动态增强。结果13例睾丸生殖细胞瘤中,3例精原细胞瘤,T1WI均呈等信号,T2WI呈稍高信号,增强呈轻度强化;1例胚胎性癌,T1WI呈低信号,T2WI呈稍高信号,增强呈明显不均匀强化;1例卵黄囊瘤,T1WI及T2WI呈高低信号,增强呈明显不均匀强化;8例混合型生殖细胞瘤,其中T1WI呈高低信号7例,呈低信号1例,T2WI呈高低信号6例,呈高信号2例,增强呈明显不均匀强化。结论睾丸生殖细胞肿瘤病理类型不同MRI表现不尽相同,MRI对睾丸生殖细胞肿瘤的诊断有一定的价值。Objective To investigate the MRI features of different pathological types of testicular germ cell tumors,and to further improve the diagnostic value of MRI in the disease.Methods The clinical and MRI data of 13 patients with pathologically proved testicular germ cell tumors were analyzed retrospectively,all the cases were performed with MRI plain scan and dynamic enhancement.Results Of the 13 germ cell tumors,3 seminomas showed isointense signal on T1WI,slightly hyperintense signal on T2WI and slightly enhanced enhancement;One case of embryonal carcinoma showed low signal intensity on T1WI and slightly high signal intensity on T2WI;One case of yolk sac tumor showed high and low signal intensity on T1WI and T2WI,and the enhancement was inhomogeneous;In 8cases og mixed germ cell tumor,7 cases showed high and low signal intensity on T1WI,1 case showed low signal intensity on T2WI,6 cases showed high and low signal intensity on T1WI,2 cases showed high signal intensity on T2WI,and the enhancement was inhomogeneous.Conclusion MRI findings of testicular germ cell tumors vary with pathological types.MRI is of certain value in the diagnosis of testicular germ cell tumors.
