Diagnosis of a uterine leiomyoma using hysteroscopy and a partial ovariohysterectomy in a mare.

The research article describes a case where a 14-year-old mare was diagnosed with a uterine leiomyoma – a type of non-cancerous tumor in the uterus, following a history of infertility and the detection of a mass in the uterine horn. The diagnosis was confirmed using investigative procedures like ultrasonography and hysteroscopy, followed by surgical intervention of a partial ovariohysterectomy.

Overview of the Case

• The subject of the study was a 14-year-old quarter horse mare which had been experiencing infertility issues for two years.
• During this period, a mass was also detected in the right uterine horn of the mare.

Diagnostic Procedures

• Initially, ultrasonography was carried out which is a type of imaging test that uses sound waves to create images of organs within the body. This helped in the preliminary identification of the mass.
• Post this, hysteroscopy was performed which involves inserting a thin, lighted tube called a hysteroscope into the vagina to examine the cervix and inside of the uterus. This procedure gave a more direct insight into the mass and its nature.

Surgical Intervention

• Based on the results from the ultrasonography and hysteroscopy, it was decided that a partial ovariohysterectomy would be performed. This is a type of surgery that involves the partial removal of the mare’s ovaries and uterus.

Confirmation of Diagnosis

• Post surgery, the removed mass was further examined histologically. This involves study of the microscopic structure of tissues.
• Upon examination, the mass was diagnosed as a uterine leiomyoma. A leiomyoma is a benign tumor of smooth muscle, the type that is found in organs such as the heart or uterus.

Conclusion

• The study focuses on the procedure to diagnose and provide surgical intervention for a case of a uterine leiomyoma in a horse, highlighting the use of ultrasonography and hysteroscopy for diagnosis, and a partial ovariohysterectomy for treatment.
