高频超声诊断小儿睾丸肿瘤的价值

Value of high-frequency ultrasound to the diagnosis of pediatric testicular tumors

目的探讨高频超声诊断小儿睾丸肿瘤的临床价值。方法回顾性分析85例经手术或穿刺活检组织病理证实睾丸肿瘤患儿的高频超声声像资料。结果高频超声提示卵黄囊瘤27例,畸胎瘤39例,白血病及淋巴瘤睾丸浸润8例,表皮样囊肿5例,单纯性囊肿6例;与组织病理检查结果进行对照,高频超声术前诊断正确76例,诊断符合率为89.4%,1例卵黄囊瘤及1例表皮样囊肿误诊为畸胎瘤,1例间质细胞瘤误诊为卵黄囊瘤,6例恶性畸胎瘤术前未明确良恶性质。结论高频超声在小儿睾丸肿瘤诊断中具有较高价值。

Objective To assess the value of high-frequency ultrasound to the diagnosis of pediatric testicular tumors.Methods The high-frequency ultrasound data of 85 patients with pediatric testicular tumor were retrospectively analyzed.Results High-frequency ultrasound confirmed yolk sac tumor in 27 patients,teratoma in 39,leukemia and lymphoma testicular infiltration in 8,epidermoid cyst in 5,and simple cyst in 6.Compared with the histopathological results,high-frequency ultrasound made correct diagnosis in 76 patients,with the coincidence rate of 89.4%.One patient with yolk sac tumor and 1 with epidermoid cyst were misdiagnosed as teratoma,1 patient with stromal tumor was misdiagnosed as yolk sac tumor,and 6 patients with malignant teratoma were misdiagnosed as benign tumors.Conclusion High-frequency ultrasound has a high value to the diagnosis of pediatric testicular tumors.
