Ovarian teratoma and endometritis in a mare.

Abstract: An 8-year-old Arabian mare was admitted for a large ovarian anovulatory follicle. A clinical diagnosis of ovarian tumor and endometritis was established. Histological examinations revealed an ovarian teratoma and a grade II endometritis. Three months after unilateral ovariectomy, the mare was confirmed pregnant and eventually gave birth uneventfully. Une jument Arabe de 8 ans fut présentée pour un gros ovaire. Un diagnostic de tumeur ovarienne et d’endométrite fut posé. L’examen histologique confirma un tératoma ovarien et une endométrite grade II. Trois mois après une ovariectomie unilaterale, la jument fut diagnostiquée gravide et mit bas sans assistance.

This research discusses a case of an 8-year-old Arabian mare diagnosed with an ovarian tumor and endometritis who was able to conceive and deliver successfully post-treatment.

Case Description

  • The research revolves around an 8-year-old Arabian mare who presented with a cystic anomaly in her ovary. A diagnosis of ovarian tumor and endometritis was made after clinical assessments.

Diagnosis and Treatment

  • Further histological examinations revealed that the ovarian tumor was actually an ovarian teratoma, a kind of germ cell tumor that arises from the ovary. In addition, a grade II endometritis was also confirmed.
  • Endometritis is an inflammation of the inner layer of the uterus, which can affect the mare’s fertility. The grading (grade II) indicates that the inflammation was moderate.
  • As part of the treatment, the mare underwent a unilateral ovariectomy, meaning only the affected ovary was removed, leaving the other intact.

Outcome and Follow-up

  • Three months after the surgery, the mare was diagnosed as pregnant, proving that the remaining ovary was functional and able to support conception.
  • The mare was then able to successfully give birth, without the need for any assistance, demonstrating that the treatment had managed the endometritis effectively and allowed for healthy pregnancy and birth.

Significance of the Study

  • The study provides valuable insights into reproductive issues in mares, especially those relating to ovarian tumours and endometritis.
  • It establishes the fact that even after the removal of one ovary and having a moderate inflammation of the uterus, the fertility of the mare can be preserved, given the appropriate treatment.
