目的探讨高频彩色多普勒超声在诊断小儿睾丸卵黄囊瘤中的应用价值。方法回顾性分析17例经病理确诊的睾丸卵黄囊瘤患儿的睾丸声像表现。结果 17例患儿中,有12例超声诊断为卵黄囊瘤,有3例误诊为睾丸间质细胞瘤,2例误诊为睾丸淋巴瘤。超声诊断准确率70.6%。结论高频彩色多普勒超声因具有安全、快速、准确的优点在诊断小儿睾丸卵黄囊瘤中具有重要意义。
Objective To investigate the value of high-frequency color Doppler ultrasound in the diagnosis of pediatric testicular yolk sac tumor. Methods A retrospective analysis of 17 cases of pathologically diagnosed testicular yolk sac tumor in children with sonographic findings. Results Of the 17 children, 12 were diagnosed as yolk sac tumor by sonography, 3 were misdiagnosed as testicular stromal tumor and 2 were misdiagnosed as testicular lymphoma. Ultrasound diagnostic accuracy of 70.6%. Conclusion High-frequency color Doppler sonography is of great importance in the diagnosis of pediatric testicular yolk sac tumor because of its safety, speed and accuracy.
