Plain-English summary
A 4-year-old male Japanese domestic cat was diagnosed with congenital hypothyroidism, which led to high calcium levels in his blood. Despite receiving fluid therapy, the cat unfortunately passed away. An examination revealed enlarged parathyroid glands and thickened blood vessel walls, indicating severe calcification. This case highlights a rare connection between hypothyroidism and secondary hyperparathyroidism, which can lead to serious health issues in cats.

Abstract
A 97-day-old male Japanese domestic cat was diagnosed as congenital hypothyroidism. During the treatment, continuous hypercalcemia was detected. Although fluid therapy was performed, the cat died at the age of 1785 days. At autopsy, both parathyroid glands were enlarged, and elastic arterial walls were increased in thickness and hardness. Histopathological examination revealed hyperplasia of both parathyroid glands and interstitial fibrosis of bilateral kidneys. Severe calcification of the tunica media and tunica externa in systemic elastic and muscular arteries were also observed. These calcifications were considered to be due to renal secondary hyperparathyroidism. In the present case, hypothyroidism might have caused hyperparathyroidism through renal failure. In veterinary medicine, this is the first reported case of hypothyroidism accompanied with hyperparathyroidism.
