Segmental uterine aplasia and ipsilateral renal agenesis in a ragdoll cat

During a routine ovariohysterectomy on a 5-month-old ragdoll cat, right-sided segmental uterine aplasia and ipsilateral renal agenesis were discovered. The diagnosis was confirmed with histopathology. This condition is congenital and is a result of a failure of embryonic development of the paramesonephric ducts. Uterine aplasia and renal agenesis is a rare finding in cats but the prevalence in the ragdoll breed appears to be higher than in the general cat population.
