目的 总结睾丸肿瘤的高频声像图特征 ,探讨高频超声在睾丸肿瘤诊断和鉴别诊断中的应用价值。方法 回顾性分析经病理证实的 37例睾丸肿瘤的高频超声及彩色多普勒血流声像图。结果 36例被诊断为睾丸肿瘤 ,敏感度为 97%。本组睾丸肿瘤具有共同声像特征 :睾丸肿大 ,睾丸纵隔声像扭曲或消失 ,有占位病灶。睾丸精原细胞瘤、畸胎瘤、睾丸囊肿和表皮样囊肿具有较为特征性的声像图。彩色多普勒超声显示睾丸恶性肿瘤内部及周边血流信号丰富 ,杂乱 ,动脉血流频谱 PSV5 .1～ 19cm/ s,RI0 .4 2～ 0 .82 ;睾丸良性肿瘤内部无或稀少的血流信号。结论 高频超声诊断睾丸肿瘤敏感性高 ,其声像图较具特征 ,高频超声结合彩色多普勒血流对鉴别睾丸肿瘤的良、恶性 ,具有较高的临床价值。
Objective To summarize the characteristics of high frequency sonography of testicular tumors and to explore the value of high frequency ultrasound in the diagnosis and differential diagnosis of testicular tumors. Methods Retrospective analysis of pathologically confirmed high-frequency ultrasound and color Doppler sonography of 37 cases of testicular tumors. Results 36 cases were diagnosed as testicular tumors with a sensitivity of 97%. Testicular tumors in this group have the common audio and video features: testicular enlargement, testicular mediastinal distortion or disappearance of audio, with occupying lesions. Testicular seminoma, teratoma, testicular cyst and epidermoid cyst have more characteristic sonograms. Color Doppler ultrasound showed rich and disorder blood flow signals inside and around the testicular malignant tumors, PSV5 .1 ~ 19cm / s, RI0.42 ~ 0.82; testicular benign tumor without or scarce blood flow signal. Conclusion High-frequency ultrasound diagnosis of testicular tumors with high sensitivity, the more characteristic sonography, high-frequency ultrasound combined with color Doppler flow to differentiate benign and malignant testicular tumors, has a high clinical value.
