Twenty-eight of 104 mature bulls in a herd were examined to determine the cause of scrotal enlargement. Ascites was determined as the source of a transudate that accumulated in and expanded the scrotal vaginal cavity to induce a scrotal hydrocele. In our experience, scrotal hydrocele in mature bulls usually is caused by the accumulation of fluids in the scrotal vaginal cavity without evidence of local inflammation or traumatic lesions. In the bulls reported here, ascites was associated with intestinal edema that was tentatively attributed to a hypersensitivity reaction to gastrointestinal nematodes. Ascites in mature bulls with scrotal hydrocele in which primary lesions of the scrotum and scrotal contents are not detected should induce practitioners to perform additional diagnostic procedures to determine the cause of the fluid.
对一群104头成年公牛中的28头进行了检查，以确定阴囊肿大的原因。腹水被确定为漏出液的来源，该漏出液积聚在阴囊鞘膜腔内并使其扩张，从而导致阴囊积水。根据我们的经验，成年公牛的阴囊积水通常是由于阴囊鞘膜腔内积液所致，且无局部炎症或创伤性病变的迹象。在此报告的公牛中，腹水与肠水肿有关，初步认为这是对胃肠线虫过敏反应所致。对于阴囊积水的成年公牛，若未检测到阴囊及其内容物的原发性病变，从业者应进行额外的诊断程序以确定液体的原因。
