原发性睾丸淋巴瘤的超声表现

The ultrasonic appearances of primary testicular lymphoma

目的探讨原发性睾丸淋巴瘤(primary testicular lymphoma,PLT)的声像图表现。方法回顾性分析16例经手术病理证实的PLT患者的超声表现,并结合病理结果进行对照分析。结果PLT可分为三型:①弥漫性均质型2例,超声表现为均质筛网状低回声,血流信号丰富呈放射状分布,镜下无明显间质纤维增生;②弥漫性不均质型9例,超声表现为分叶状或地图状不均质低回声,血流信号丰富呈线状分布,镜下间质纤维不同程度增生形成纤维分隔;③局灶性结节型5例,超声表现为均匀低回声结节,血流信号不丰富,镜下间质纤维增生包绕瘤体。结论PLT的超声表现与病理学改变密切相关,认识两者的关系有助于提高超声的诊断价值。

Objective To explore the sonographic features of primary testicular lymphoma(PLT).Methods The sonographic features of 16 PLT patients confirmed by surgery and pathology were retrospectively analyzed.Results Sixteen PLT patients were typed into 3 ultrasonic patterns:①The diffuse homogeneous echo type:2 cases,the ultrasonic features were homogeneous sieve-like hypoechoic echo,the blood flow signal was rich and radially distributed,with interstisial fibrosis inapparently under-microscope.②The diffuse uneven homogeneous echo type:9 cases,the ultrasonic features lobulated or map-like heterogeneous hypoechoic features,the blood flow signal was rich in linear distribution,and interstisial fibrosis proliferated to form fibrous septa under-microscope.③The focal nodular pattern echo type:5 cases,the ultrasonic features were homogeneous hypoechoic nodules,the blood flow signal was few,interstisial fibrosis hyperplasia surrounding the tumor under-microscope.Conclusions Ultrasonic appearances of primary testicular lymphoma are closely related to its pathologic characteristics,the recognization of their relations contributes to improve the diagnostic value of ultrasound.
