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 investigate the clinical value of high frequency ultrasound in the diagnosis of pediatric testicular tumors. Methods A retrospective analysis of 85 cases of children with testicular tumors confirmed by surgery or needle biopsy was performed with high-frequency ultrasonography. Results High frequency ultrasound showed that there were 27 cases of yolk sac tumor, 39 cases of teratoma, 8 cases of leukemia and lymphatic invasion, 5 cases of epidermoid cyst and 6 cases of simple cyst. Compared with the results of histopathological examination, 76 cases were correctly diagnosed, the diagnostic coincidence rate was 89.4%, 1 case of yolk sac tumor and 1 case of epidermoid cyst were misdiagnosed as teratoma, 1 case of mesenchymal tumor misdiagnosed as yolk sac tumor, 6 cases of malignant teratoma before operation Not clear good and evil nature. Conclusion High-frequency ultrasound in pediatric testicular cancer has high value.
