Nonreducible Inguinal Hernia Containing the Uterus and Bilateral Adnexa in a Rhesus Macaque ().

Abstract

Inguinal herniation of abdominal viscera is a relatively common condition in both humans and domestic animal species. In captive rhesus macaques (Macaca mulatta), the highest incidence occurs in overweight, aged males. However, inguinal herniation of the uterus with bilateral adnexa is extremely rare in both human and veterinary medicine. Here we report a previously undescribed uterine inguinal herniation with bilateral adnexa in a 3-y-old female rhesus macaque. Although uterine herniation remains a rare condition in rhesus macaques, it should be considered as a differential diagnosis in animals with unilateral subcutaneous enlargements in the inguinal region.
