Ovarian remnant syndrome in a cat with ectopic ovary

Abstract

Ovarian remnant syndrome is the most recognized complication of female cat neutering. Confident unequivocal diagnosis based on clinical signs, ultrasonography of the entire abdomen and specific endocrine tests (anti-Müllerian hormone [AMH]) is essential prior to surgical investigation and management. This present paper describes the case of 2 years old female cat, evaluated for recurring estrus behavior after ovariohysterectomy and one subsequent exploratory laparotomy in which persistent ovarian tissue was not found at the site of an ovarian pedicle. Our findings emphasized the importance of a correct diagnostic protocol prior to surgery and the necessity to explore the entire abdominal cavity when evaluating a patient for possible ovarian remnant tissue. Additionally, is necessary to confirm the excision of ovarian remnant tissue by histologic assessment.
