RESUMO
OBJECTIVE: To describe the clinical presentation, clinical course, and management of a dog with thyroid storm (TS) secondary to a functional thyroid carcinoma. CASE SUMMARY: A 12-year-old neutered female Golden Retriever was evaluated for severe weight loss, hyperthermia, and tachycardia. The dog had a ventral neck mass and markedly increased thyroxine concentration. Cervical ultrasound showed a suspected left thyroid mass with invasion into the jugular vein. Despite aggressive therapy, the patient progressed to a clinical TS. Postmortem examination was supportive of the clinical diagnosis. NEW OR UNIQUE INFORMATION PROVIDED: To the authors' knowledge, this is the first report of TS in a dog.

In human medicine, thyroid storm is a well-recognized condition of acute thyrotoxicosis in which the patient's metabolic, thermoregulatory, and cardiovascular mechanisms are overwhelmed by excessive circulating levels of thyroid hormone. The etiology is unknown, but multiple precipitating factors have been proposed. Hyperthyroid cats presenting in thyrotoxic crisis have clinical signs similar to those of human thyroid storm patients; however, thyroid storm has not yet been fully characterized in veterinary medicine. Early recognition and prompt, appropriate treatment of this life-threatening condition are essential to obtaining a favorable outcome.

Thyroid storm is a syndrome described in human medicine to define a multisystemic disorder resulting from organ exposure to excessive levels of thyroid hormone. This form of acute thyrotoxicosis, although uncommon, can be life threatening and is a significant cause of mortality in human emergency rooms. Although thyroid storm is a well-recognized clinical entity in human medicine, it has not been described in veterinary medicine. This article discusses the human syndrome and defines a similar syndrome in hyperthyroid veterinary patients. The clinical signs of and treatment modalities for feline thyroid storm are also presented.
