The owner reported that the right swelling had been present for several months and that it was reducible. The animal had normal urination, behaviour and appetite, but experienced weight loss. The horse did not manifest any of the other characteristic signs reported in the literature, such as chronic constipation, tenesmus and difficulty in urination. There was no evidence of severe dehydration or infection. The mare was aged, and had foaled four times. In addition, according to the Caslick Index, she also had a poor vulvar conformation (Figure 3). All these factors can lead to perineal muscle weakness. This situation could predispose to herniation.
