Objective To discuss the diagnostic and differential diagnostic value of ultrasonography for primary 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.
目的 通过总结韧带样型纤维瘤病（DF）的超声图像表现和病理学结构，以提高对DF的认识和诊断水平。 方法 回顾性分析2005年1月－2011年12月70例经手术和病理组织学证实为DF患者的超声图像和病理组织学结果。 结果 DF肿块的超声表现与病理结构密切相关。70例DF中腹部外型41例（58.6%）、腹壁型18例（25.7%）、腹内型11例（15.7%）。DF的典型超声图像表现为沿肌纤维浸润性生长的低回声肿块,累及多块肌肉；肿块无包膜,多数形态不规则、边界不清；其中8例包绕和侵犯相邻骨质, 12例肿瘤压迫或侵犯邻近血管、神经、肠管等组织；40例瘤体内探及Ⅰ级血流信号，4例探及Ⅲ级血流信号；所有病变均未见坏死出血和囊变，病变周围无淋巴结肿大。 结论 DF的声像图表现有较强的特征性，超声能较为准确判断肿块累及范围、是否侵犯相邻骨质、与毗邻血管、神经的关系，有助于制定手术计划。
