A unique phenotypical presentation of a male pseudohermaphrodite in a dairy bull calf

Abstract

A six month old Brown Swiss bull calf was referred for surgical correction of a scrotal hernia. Palpation and ultrasoography of the scrotum revealed a freely movable luminal structure in the right side of the scrotum and one descended testicle in the left portion of the scrotum. The clinical management plan included surgical correction of the small intestinal inguinal herniation followed by bilateral castration. The calf was anesthetized and taken to surgery. While performing the surgical procedure, it was discovered that intestines were not the structures involved in the hernia but rather were structures of the Müllerian duct system; the cervix and uterine horns were found within the scrotum. Additionally, the right testicle was attached to the right uterine horn and retained within the right inguinal canal. The uterus, cervix, and bilateral testes were ligated and surgically removed. The inguinal ring was surgically closed in order prevent further herniation. The calf recovered without complications and was returned to the owner.
