Plain-English summary

A 7-year-old female beagle was brought in for high calcium levels and symptoms of hypothyroidism, which can include weight gain, lethargy, and skin issues. After ruling out other causes with various tests, the vet started her on thyroxine, a medication to help with thyroid function. Remarkably, her calcium levels returned to normal after about 9 weeks of treatment. This case is notable as it's the first report linking adult-onset hypothyroidism with high calcium levels in dogs.

Abstract

A 7-year-old female beagle was evaluated for symptomatic hypercalcaemia and primary hypothyroidism. Clinical findings were typical for hypothyroidism. Plasma parathyroid hormone was low and obvious causes for the hypercalcaemia were ruled out by means of abdominal ultrasonography, ultrasonography of the parathyroid glands, survey thoracic radiographs, and fine needle aspirate cytology of the spleen, liver, and peripheral lymph nodes. Treatment with thyroxine resulted in resolution of the hypercalcaemia after approximately 9 weeks of therapy. This is the 1st report of primary adult-onset hypothyroidism associated with symptomatic hypercalcaemia in a dog.
