Case of equine goitre

Area of Science:

• Veterinary Medicine
• Endocrinology
• Equine Health

Background:

• Equine goitre, or enlargement of the thyroid gland in horses, is a condition with various potential causes.
• Congenital goitre presents at birth, impacting foal health and survival.
• Literature review highlights existing knowledge gaps and clinical presentations of equine goitre.

Observation:

• A case study of a foal with congenital goitre is presented.
• Clinical signs included a localized neck swelling, hyperextension of lower limbs, and initial difficulties with nursing.
• The foal exhibited significant physical challenges due to the congenital condition.

Findings:

• Surgical removal of the goitre was performed.
• Hyperextension of the limbs was successfully managed using specialized surgical shoes and bandaging techniques.
• The probable etiology identified was a combination of dietary iodine deficiency and the presence of goitrogens in the mare's diet.

Implications:

• This case demonstrates the successful surgical and supportive treatment of congenital goitre and associated hyperextension in foals.
• Understanding the role of iodine deficiency and dietary goitrogens is crucial for preventing equine goitre.
• Effective management strategies can improve foal survival rates and long-term health outcomes.
