目的：分析原发性睾丸淋巴瘤的M RI表现，从而提高对该病的影像学认识。方法对7例经手术病理证实的阴囊内原发性睾丸淋巴瘤的M RI表现进行回顾性分析，观察病灶的形态特征、信号强度并与病理形态学表现进行对照。结果6例表现为单侧睾丸发病，1例为双侧睾丸发病。7例肿瘤均呈弥漫性占位，M RI表现T1 WI呈等、低信号，T2 WI大致均匀稍低信号3例；4例T1 WI信号不均匀，可见片状高信号，T2 WI呈以低信号为主的混杂信号；DWI（b值＝1000）7例均表现为高信号；增强扫描病灶呈轻度或显著不均匀强化，坏死区无强化；睾丸鞘膜积液2例，同侧附睾、精索受累1例；7例免疫表现类型均为B细胞，弥漫大细胞型。结论原发性睾丸淋巴瘤的M RI表现有一定的特征，结合临床病史有助于诊断和鉴别诊断。

Objective To improve the diagnosis of primary testicular lymphoma through the analysis of MRI features .Methods The MRI findings of seven patients with pathologically proved primary testicular lym-phoma were retrospectively reviewed .Morphological characteristics of the lesion ,the signal strength and perfor-mance were compared with pathology .Results 6 cases were unilateral and 1 was bilateral .All PTL show as dif-fuse lesions ,and were isointense on MRI T1 WI ,on T2 WI ,the lesions showed homogeneous low signal intensi-ty in 3 patients ,mainly hypointense in 4 patients which T1 WI signal is not uniform ,and were found in small pieces of high signal .All PTL showed as high signal on DWI (the value of b=1 0 0 0 ) .Hydrocele was found in 2 patients ,and tumor invading the epididymis or spermatic cord was noticed in 1 patient .Enhanced scan showed mild to obvious inhomogeneous enhancement ,no enhancement of the necrotic area .7 case of immune types were large B -cell ,diffuse cell type .Conclusion MRI characteristics of PTL are distinctive in certain extent .Com-bining with clinical history contributes to the diagnosis and differential diagnosis of PTL .
