A 14-year-old domestic short-haired cat was examined for a recurrent arteriovenous fistula of the left elbow. Hyperthyroidism associated with multinodular adenomatous hyperplasia of the right thyroid gland was also diagnosed. Cardiovascular abnormalities associated with the vascular shunt and feline hyperthyroidism were noted. The delineation of the two concurrent diseases was based upon the results of a forelimb radiographic dye study, thyroid hormone assay, radionuclide scanning of the thyroid glands, and histopathologic evaluation of the excised right thyroid gland. The cat exhibited marked clinical improvement following amputation of the left foreleg and excision of the right thyroid gland. Six months later, the cat ,was euthanized following identification of an infiltrative sublingual squamous cell carcinoma.
