摘　　要：目的:探讨睾丸肿块MRI的表现及诊断价值。方法:回顾性分析23例病理证实睾丸肿块,所有病例均行MRI平扫及增强扫描,观察肿块的形态特征、信号、强化程度及周围情况。结果:23例肿块中:精原细胞瘤7例,混合性生殖细胞瘤3例,畸胎瘤3例,内胚窦瘤2例,表皮样囊肿1例,Leydig细胞瘤1例,淋巴瘤1例,非特异性炎性肿块3例,结核2例。MRI对睾丸肿块定位准确,大多数肿块具有一定特征性。结论:根据MRI表现,结合临床病史,多数睾丸肿块可做出正确诊断。Objective： To study the MRI manifestation of testicular tumor and the value of MRI in the diagnosis of the disease. Methods ： We retrospectively analyzed 23 cases of pathologically confirmed testicular tumor, and observed the morphological character- istics, signals and surrounding conditions of the tumor using plain and enhanced MRI scanning. Results ： Of the 23 cases, seminoma was identified in 7, mixed germinoma in 3, teratoma in 3, endodermal sinus tumor in 2, epidermoid in 1, Leydig cell tumor in 1, leu- coma in 1, nonspecific inflammatory mass in 3, and tuberculosis in 2. MRI revealed the precise locations and specific characteristics of the tumors. Conclusion - Based on MRI findings and Clinical manifestation, most testicular tumors can be diagnosed correctly.
