A 2-year-old Standardbred gelding was examined because of prolapse of the third eyelid; myoclonus of the muscles of the head, neck, and forelimbs; and persistent tail swishing. The horse had a high plasma sodium concentration but was not drinking water. The hypernatremia could not be corrected by means of IV administration of fluids, and the horse became worse and, 6 days later, died. At necropsy, a tumor was found to be compressing the neurohypophysis and the area in the brain in which the thirst centers are believed to be located. It is believed that hypernatremia in this horse was a result of altered thirst.
一匹2岁的标准赛马因第三眼睑脱垂、头部、颈部和前肢肌肉阵挛以及持续摆尾而接受检查。这匹马血浆钠浓度高，但不饮水。静脉补液无法纠正高钠血症，马的病情恶化，6天后死亡。尸检时发现一个肿瘤压迫神经垂体和大脑中据信是渴觉中枢所在的区域。据信这匹马的高钠血症是渴觉改变所致。
