睾丸附件扭转的超声诊断

Ultrasonic diagnosis of appendix testis torsion

目的探讨睾丸附件扭转的超声诊断价值。方法回顾性总结近5年睾丸附件扭转22例超声声像图表现。结果睾丸附件扭转1周内声像图表现为睾丸与附睾间出现圆形、类圆形或棒状结节,较正常明显增大,回声减低,结节内部呈网状,可伴同侧睾丸及附睾肿大、阴囊壁增厚、睾丸鞘膜积液。CDFI示结节内无血流信号,同侧附睾头和睾丸血流信号较丰富。1周后声像图表现为睾丸附件体积明显缩小,回声增高,同侧附睾及睾丸体积逐渐恢复正常,鞘膜积液渐渐消失,阴囊壁接近正常。结论超声对睾丸附件扭转具有较高的诊断价值。

Objective To study the ultrasound diagnosis value of appendix testis torsion.Methods Ultrasonography of 22 cases with appendix testis torsion in our hospital were summarized retrospectively.Results When testicular appendage reverse,round,oval or patchy nodules,the size from 3 to 20mm, appeared between the testis and epididymis in 1 week,these nodules with low echo,even net changes,Significantly large than the normal.Sometimes,Enlargement of the ipsilateral testis and epididymis,scrotal wall thickening,hydrocele could also occur.CDFI showed no significant blood flow within the nodules,but ipsilateral epididymal head and testicular blood flow signals were more abundant.After 1 week,testicular appendage volume was significantly reduced,at the same time echo higher;ipsilateral epididymis and testicular volume and blood flow gradually returned to normal.Conclusion ultrasound is the Preferred method to diagnose the torsion of testicular appendage.
