Plain-English summary
A 12-year-old Morgan mare was brought in for acting like a stallion for 45 days. During the examination, the vet found a large left ovary with cysts and signs of abdominal pain. Surgery revealed that the ovary had twisted 720 degrees and was severely damaged, likely due to a granulosa-theca cell tumor. The vet corrected the twist and removed the ovary, and the mare recovered well after surgery. This case highlights the importance of considering ovarian torsion in mares with known ovarian issues if they show signs of pain.

Abstract
A 12-year-old Morgan mare was examined because of stallion-like behavior of 45 days' duration. Palpation per rectum and transrectal ultrasonographic examination revealed a large left ovary with multiple cystic areas and crepitus. A granulosa-theca cell tumor was suspected. During hospitalization for further evaluation of the affected ovary, the mare developed signs of abdominal pain. Exploratory surgery revealed a large left ovary, which was black with a necrotic and friable surface, and a 720 degrees clock-wise torsion of the ovarian pedicle. Torsion was corrected, and oophorectomy was performed. The mare recovered satisfactorily from surgery. Histologic diagnosis was granulosatheca cell tumor with marked diffuse necrosis. To our knowledge, torsion of the ovarian pedicle has not been reported in the veterinary literature. However, it is not uncommon in women. Ovarian torsion seems to develop in association with neoplasia, cysts, and ovarian hyperstimulation syndrome. Ovarian torsion should be considered as a differential diagnosis for mares with a known ovarian pathologic change such as neoplasia or abscess if signs of abdominal pain are evident.
