Using ultrasound (US), we studied seven patients with torsion of the spermatic cord associated with a large amount of extratesticular hemorrhage. In each case, US showed a large echogenic or complex extratesticular mass caused by the hemorrhage, in addition to a hypoechoic testis and scrotal skin thickening. This appearance should be recognized as part of the spectrum of sonographic appearances that can be seen in torsion.
我们使用超声（US）对7例伴有大量睾丸外出血的精索扭转患者进行了研究。在每例患者中，超声显示除了低回声的睾丸和阴囊皮肤增厚外，还有一个由出血引起的大的高回声或混合性睾丸外肿块。这种表现应被视为扭转中可见的超声表现谱的一部分。
