Plain-English summary
A 2-year-old female cat was brought in because she was showing signs of going into heat again after being spayed. Despite a previous surgery to check for leftover ovarian tissue, nothing was found. The veterinarians used ultrasound and specific hormone tests to help diagnose her condition, which is known as ovarian remnant syndrome, a complication that can occur after spaying. They emphasized the importance of thorough testing before any surgery to ensure that any remaining ovarian tissue is properly identified and removed.

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.
