摘　　要：目的分析并总结原发性睾丸淋巴瘤(primary testicular lymphoma,PTL)的超声图像特征,探讨超声对其诊断价值。方法选择2005年—2015年经术后病理组织学确诊为PTL的患者31例,对其PTL声像图表现及临床资料进行回顾性分析。结果 PTL好发于老年男性,以无痛性睾丸肿大为首发症状。31例患者中,累及单侧睾丸23例、双侧睾丸8例,共计39个睾丸。灰阶超声根据病灶的大小及分布,可分为弥漫型22例,结节型9例。超声表现为睾丸内出现低回声病灶,部分内可见线状强回声,病灶血流信号丰富,动脉阻力指数为低阻。结论老年男性出现无痛性的睾丸肿大时,首先要考虑到PTL的可能性。PTL的超声图像有一定的特征性,结合临床病史有助于诊断和鉴别诊断。Objective Todiscussthediagnosticanddifferentialdiagnosticvalueofultrasonographyforprimary testicular lymphoma （PTL） by studying the ultrasonographical image characteristics. Methods Thirty-one patients with PTL confirmed by postoperative histopathology between 2005 and 2015 were chosen to be the study subjects. We retrospectively analyzed their ultrasonographical features and clinical data. Results Most PTL patients were elderly men, and the initial symptom was mainly painless testis enlargement. Thirty-nine testicles were involved in the primary testicular lymphoma, including 23 unilateral and 8 bilateral. In the 31 patients, 22 had diffuse lesions and 9 nodal. Ultrasonography showed that most tumors were hypoechoic lesions, and part of them were hyperechoic linearly. The lesions had abundant blood flow signals with a low resistance index. Conclusions In elderly patients with painless testicular enlargement, the possibility of primary testicular lymphoma must be fist considered. Manifestations of primary testicular lymphoma have some distinctive characteristics, and combined with clinical history, they are helpful for the diagnosis and differential diagnosis of PTL.
