目的总结睾丸表皮样囊肿的高频彩超声像特征,探讨高频彩超诊断睾丸表皮样囊肿的价值。方法回顾性分析11例经手术组织病理证实睾丸皮样囊肿患者的高频彩超声像资料,计算超声术前诊断睾丸表皮样囊肿的符合率。结果超声显示病灶边界清晰10例,边界模糊1例;病灶声像图表现为“洋葱圈”型6例,“蛋壳样”钙化型3例,肿块型2例;病灶内均无明显血流信号显示;超声术前诊断睾丸表皮样囊肿9例,2例肿块型睾丸表皮样囊肿误诊为睾丸精原细胞瘤;与手术组织病理检查结果对照,超声术前诊断睾丸表皮样囊肿的符合率为81.8%。结论睾丸皮样囊肿的高频超声声像表现具有一定特异性,高频彩超在睾丸皮样囊肿的诊断中具有较高价值。
Objective To summarize the characteristics of high frequency color ultrasound imaging of epidural dermoid cysts and to explore the value of high frequency color Doppler ultrasonography in the diagnosis of epidural dermoid cysts. Methods A retrospective analysis of 11 cases of histologically confirmed testicular dermoid cysts in patients with high frequency color Doppler ultrasound data to calculate the preoperative ultrasound diagnosis of epidural testis cystic compliance. Results Ultrasound showed that the border of the lesion was clear in 10 cases and the boundary was blurred in 1 case. The sonographic findings of lesion included 6 cases of “onion ring” type, 3 cases of “egg-shell type” calcification, 2 cases of mass type, No obvious blood flow signal was observed. Ultrasound preoperative diagnosis of epidural dermoid cyst in 9 cases, 2 cases of testicular epidermoid cyst misdiagnosed as testicular seminoma; and surgical histopathological examination results, ultrasound diagnosis of testicular epidermoid cysts The coincidence rate was 81.8%. Conclusion High frequency ultrasound imaging of testicular dermoid cysts has certain specificity. High frequency ultrasound is of high value in the diagnosis of testicular dermoid cysts.
