Ultrasound as an aid for diagnosis of ovarian abscesses in two mares.

This research article provides a report on how ultrasound was used to help diagnose ovarian abscesses, a medical condition, in two different horses that showed symptoms such as lack of appetite, unexplained fever, and weight loss.

Research Context

• The research investigates two specific cases where two mares – female horses – were exhibiting similar symptoms – anorexia or lack of appetite, fever of unknown origin, and weight loss. The tentative diagnosis after conducting clinical examinations and laboratory tests, supported by transrectal ultrasonography, was ovarian abscessation.

Research Methodology

• Ultrasound, specifically transrectal ultrasonography, is used to capture images that might confirm the suspicion of ovarian abscesses.
• Postmortem examination on one horse, which was euthanized due to financial considerations and therefore could not be treated, enabled the researchers to physically inspect the condition of the ovaries and indications of abscesses.

Research Findings

• The first mare responded positively to medical treatment post-diagnosis.
• The necropsy of the second mare confirmed the diagnosis. It revealed an enlarged right ovary adhered or stuck to the large colon, a major part of the horse’s digestive system.
• Analysis under the microscope of samples from the necropsy further confirmed the presence of an ovarian abscess.

Research Significance

• This research attests to the utility of ultrasound as a diagnostic tool in identifying serious health conditions in animals, in this case, horses. It lends confidence to the veterinary community about the uses of ultrasound to arrive at accurate diagnoses for symptoms like anorexia, fever, and weight loss in horses, allowing for timely and pertinent medical intervention.
• The confirmation of ovarian abscesses via postmortem examination further demonstrates the physical manifestation of the abscess and can be used as educational material for the diagnosis of future cases.
