Progressive ethmoidal haematoma in horses.

The research discusses the occurrence and treatment outcomes of progressive ethmoidal hematoma, a type of sinus tumor, in horses. There were 14 horses of varying breeds and ages in the study, and their diagnoses were confirmed through various methods. The research examined treatment efficacy, which involved either non-surgical methods or surgery, and noted varying degrees of success.

Demographics of Diagnosed Horses

• The study involved a total of 14 horses; 12 were Thoroughbreds, one was part-Arab, and one was a stock horse. The ages of the horses ranged from 3 to 18 years, and both genders were represented in the study.
• The diagnosis of progressive ethmoidal haematoma in these horses was based on the history of the horses, clinical signs, endoscopy and radiographic results. Histologic confirmation was received in 10 of these cases.
• Approximately 78% of the lesions were unilateral, meaning they impacted one side of the sinus, while 22% were bilateral and affected both sides.

Treatments and Outcomes

• Of the 14 horses, two were euthanized immediately upon diagnosis. Four horses received conservative treatment which did not involve surgical intervention. Of these, three were euthanized between 6 to 24 months post-diagnosis due to the progression of their conditions, and one horse had its condition fully resolved within 13 months.
• Eight horses underwent surgery for the removal of the tumor. Three horses died in the post-operative phase, and another three horses had to be euthanized within 48 months post-surgery due to recurrence of the condition. However, two horses did not demonstrate any recurrence of the condition for 60 and 72 months respectively.

Summary

• The study reveals that progressive ethmoidal hematoma in horses is a severe condition with varied treatment outcomes. While conservative treatment has been successful in some instances, its overall effectiveness appears limited, with several cases seeing conditions worsen post-treatment. Surgical removal of the tumor has had a somewhat higher rate of success, though recurrence of the condition is a significant risk, leading to further health complications and potential euthanasia.
