To investigate the high-frequency ultrasonographic characteristics and clinical features of primary testicular lymphoma (PTL) in children.
We retrospectively analyzed the high-frequency ultrasonographic manifestations and clinical characteristics of 11 cases of PTL in children, all confirmed by postoperative pathology.
Most of the PTL patients were school-age children, with painless testicular enlargement as the initial symptom. Preoperative grey-scale ultrasonography showed involvement of the unilateral testis in 8, bilateral testes in 3, and both the testis and epididymis in 2 of in the 11 children with PTL. Nine of the cases were displayed as diffuse lesion and the other 2 as nodular lesion, all with extremely low echogenicity. Color Doppler flow imaging (CDFI) revealed abundant blood flow signals but no liquefaction or calcification echo in the lesions. Follow-up ultrasonography after immunochemotherapy showed complete disappearance of the lesion in 3 cases, reduction in another 3, no significant change in 1, and enlargement in the other 4.
PTL in children has some specific ultrasonographic characteristics. A deeper insight into the ultrasonographic characteristics and clinical features of PTL may help improve ultrasonographic diagnosis of the disease.
探讨儿童原发性睾丸淋巴瘤（PTL）的高频超声特征及临床特点。
回顾性分析11例经术后病理证实的儿童PTL的高频超声表现及临床特征。
PTL患者多为学龄儿童，以无痛性睾丸肿大为首发症状。术前灰阶超声显示，11例PTL患儿中，8例为单侧睾丸受累，3例为双侧睾丸受累，2例睾丸及附睾均受累。9例表现为弥漫性病变，2例为结节性病变，均为极低回声。彩色多普勒血流成像（CDFI）显示病变内血流信号丰富，无液化或钙化回声。免疫化疗后随访超声显示，3例病变完全消失，3例缩小，1例无明显变化，4例增大。
儿童PTL具有一些特定的超声特征。深入了解PTL的超声特征及临床特点可能有助于提高该病的超声诊断水平。
