Plain-English summary

An 11-year-old male Golden Retriever was having problems like losing weight, a fast heartbeat, high body temperature, and peeing and drinking a lot. The vet found a movable lump in his neck that was about the size of a small orange. Tests showed that he had high levels of thyroid hormones, leading to a diagnosis of hyperthyroidism caused by a thyroid tumor. The tumor was surgically removed, and afterward, his hormone levels went down, and he started feeling better. A year later, he was doing well with no signs that the tumor had come back.

Abstract

An 11-year-old male Golden Retriever presented with progressive weight loss, tachycardia, hyperthermia, polyuria and polydipsia. A freely movable mass, 4.5 x 4 cm in size, was palpated at the cranioventral cervical region. Hormonal study revealed high levels of serum thyroid hormones, and a tentative diagnosis of hyperthyroidism due to a thyroid tumor was made. The tumor was removed surgically and diagnosed histopathologically as thyroid gland adenoma. Serum thyroid hormone levels decreased after surgery with improved clinical signs. At 12 months after surgery, the dog maintained a good physical condition with no evidence of recurrence.
