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 To analyze and summarize the ultrasonographic features of primary testicular lymphoma (PTL) and investigate the diagnostic value of ultrasound. Methods Thirty-one patients with PTL diagnosed by postoperative histopathology from 2005 to 2015 were retrospectively analyzed on their PTL sonographic findings and clinical data. Results PTL occurs in older men, with painless testicular swelling as the first symptom. Of the 31 patients, 23 had unilateral testes and 8 had bilateral testes, a total of 39 testes. Grayscale ultrasound lesions according to the size and distribution can be divided into diffuse type 22 cases, nodular 9 cases. Ultrasound showed hypoechoic lesions in the testes, part of the linear hyperechoic seen in the lesion rich blood flow signal, arterial resistance index is low resistance. Conclusion In elderly men with painless testicular enlargement, we must first consider the possibility of PTL. PTL ultrasound images have a certain characteristic, combined with clinical history contribute to the diagnosis and differential diagnosis.
