Plain-English summary
A 16-year-old Thoroughbred mare was found to have a serous cystadenoma, which is a type of tumor, in her right ovary after a thorough examination. Despite having normal heat cycles, she had an unusually high number of follicles in that ovary and elevated testosterone levels in her blood. After the tumor was surgically removed, her testosterone levels returned to normal. This suggests that the treatment was successful in resolving the issue.
Abstract
Serous cystadenoma was diagnosed by histologic examination of a large ovary removed from a 16-year-old Thoroughbred mare with normal estrous cycles. Palpation and ultrasound examination per rectum had revealed an excessive number of follicles in the right ovary. The ovulation fossa was palpable on the right ovary, and the left ovary appeared to have normal activity. Plasma testosterone values were high at the time of examination (0.15 ng/ml), but decreased to normal values (0.09 ng/ml) after removal of the cystadenoma.
