Theriogenology Question of the Month

History A 2-year-old sexually intact male Vietnamese potbellied pig that weighed 113 kg (249 lb) was admitted and examined to determine the cause of inappetance, irritability, and an enlargement in the inguinal region. The clinical signs had become more evident and the pig’s condition had gradually worsened during the preceding week. No treatment had been initiated prior to our examination. The owners reported that the boar would attempt to mate with a piece of polyvinyl chloride pipe. Physical examination revealed massive distention (40 X 25 cm [15.7 X 9.8 inches]) in the inguinal region and caudoventral portion of the abdomen. Palpation of the enlargement revealed it was firm and excessively warm but could be compressed, which suggested it was filled with fluid. The prepuce was edematous. There was evi dence of irritation of the skin over the right inguinal region. Question
