Plain-English summary
An 8-month-old male domestic shorthaired cat was brought to the vet because he was losing weight, having trouble breathing sometimes, experiencing chronic diarrhea, being overly active, and feeling weak. The vet found a lump on his thyroid and noticed high levels of certain thyroid hormones in his blood, leading to a diagnosis of hyperthyroidism (an overactive thyroid). The cat had surgery to remove one of his thyroid glands and later received radioactive iodine treatment. After the radioactive iodine treatment, his symptoms improved, but he then developed hypothyroidism (an underactive thyroid).
Abstract
An 8-month-old, male domestic shorthaired cat presented for chronic weight loss, intermittent dyspnea, chronic diarrhea, hyperactivity, and weakness. The cat had a palpable thyroid nodule and increased serum total thyroxine and 3,5,3' triiodothyronine levels. The cat was diagnosed with hyperthyroidism, and a unilateral thyroidectomy was performed followed by radioactive iodine at a later date. The clinical signs resolved following radioactive iodine, and the cat subsequently developed clinical hypothyroidism.
