[Congenital goiter in the neonatal foal. Two case reports. Zwei Fallberichte].

This study explores two cases of congenital hyperplastic goiter in newborn horses, detailing the sonographic assessment and associated symptoms for each. One case resulted in euthanization due to severe symptoms and a poor prognosis, while the other case resolved with symptomatic treatment.

Overview of the Study

• The research document presents two unique cases of congenital hyperplastic goiter in foals. Congenital hyperplastic goiter is a rare condition characterized by an abnormally enlarged thyroid gland.
• The study specifically focused on recording the symptoms, conducting a sonographic evaluation of the swollen thyroid gland, and documenting the progression or regression of the disease in the foals.

First Case Study

• In the first case, the foal suffered not just from the enlarged thyroid gland but also had skeletal deformities. These included mandibular prognathism, a condition where the lower jaw protrudes farther out than the upper jaw, and contractures or permanent shortening of the muscles or tendons in the forelimbs.
• Due to the severity of the symptoms and a poor prognosis, it was decided to euthanize the animal.

Second Case Study

• The second case involved a premature foal that reported respiratory issues alongside the hyperplastic goiter. It suggests that the condition might also affect the respiratory functions.
• Unlike the first case, this foal was given symptomatic treatment. The details of the treatment aren’t specified but generally, symptomatic treatment aims to alleviate the symptoms of a disease rather than cure it. This therapy resulted in the regression of goiter within a few weeks, indicating the potentially treatable nature of this condition when not coupled with severe complications.

Conclusion

• This research provides valuable case studies for future reference about congenital hyperplastic goiter in foals. It indicates the possible outcomes of the condition, symptoms that can coincide it, and highlights the potential for symptomatic treatment in leading to the regression of the disease.
