Plain-English summary
A 9-year-old American Saddlebred mare was taken to the vet because her belly was swollen and she was showing signs of pain. A procedure to collect fluid from her abdomen showed that there was a lot of blood present. Further examinations, including a rectal check and an ultrasound, found a large growth at the end of her right uterine horn. Unfortunately, the mare was put to sleep for humane reasons, and a post-mortem examination revealed that the growth was a granulosa-thecal cell neoplasm, which is a type of tumor that can cause infertility or unusual sexual behavior. In this case, the bleeding in her abdomen was a rare complication linked to the tumor.
Abstract
A 9-year-old American Saddlebred mare was referred because of abdominal distention and signs of abdominal pain. Copious peritoneal fluid obtained by abdominocentesis appeared to be frank blood. Rectal and ultrasonographic evaluation of the abdomen revealed a large mass at the distal tip of the right uterine horn. The mare was euthanatized and necropsied and the mass was determined to be a granulosa-thecal cell neoplasm. The most common clinical sign of granulosa-thecal cell neoplasm is infertility or abnormal sexual behavior. Hemoperitoneum is infrequently associated with neoplasms in horses.
