A 360-degree torsion of the left spermatic cord was diagnosed in a 2 1/2-year-old Quarter Horse colt. Clinical signs included abdominal discomfort, with slight elevations in heart and respiratory rates. The scrotum on the left side was moist and edematous. The left testicle was enlarged, firm, and retracted slightly toward the abdominal cavity. The colt resented palpation of the testicle. On rectal palpation, the left vaginal ring and the structures passing through the ring were edematous and painful to pressure. Surgical correction was achieved by emasculation. The tail of the epididymis and an elongated portion of the body of the epididymis were attached to the left testicle by an unduly long mesorchium. The caudal ligament of the epididymis and the proper ligament of the testis were elongated. These anatomic variations may have predisposed to torsion of the spermatic cord.
一匹2岁半的夸特马驹被诊断为左侧精索发生360度扭转。临床症状包括腹部不适，心率和呼吸频率略有升高。左侧阴囊潮湿且水肿。左侧睾丸肿大、坚硬，并稍向腹腔回缩。马驹抗拒对睾丸的触诊。直肠触诊时，左侧腹股沟管内环及通过该环的结构水肿，按压时有疼痛感。通过去势手术进行了矫正。附睾尾部和附睾体的一段延长部分通过过长的睾丸系膜附着于左侧睾丸。附睾尾韧带和睾丸固有韧带延长。这些解剖变异可能易导致精索扭转。
