Plain-English summary

A 14-year-old domestic short-hair cat was brought to the vet because it had been feeling unwell at times and drinking more than usual. The vet diagnosed the cat with hyperthyroidism (an overactive thyroid) and cholelithiasis (gallstones) using blood tests and imaging techniques like X-rays and ultrasounds. The cat was treated for hyperthyroidism and then underwent surgery to remove both the thyroid gland and the gallstones, which were made of calcium and bilirubin. Further examination of the tissues indicated that the cat also had some mild issues with its pancreas and liver, which may have played a role in the formation of the stones. The treatment was successful.

Abstract

A 14-year-old domestic short-hair cat presented with a history of intermittent malaise and increased drinking. A diagnosis of hyperthyroidism and cholelithiasis was made by a combination of blood testing, radiography and ultrasonography. After medical management of hyperthyroidism, thyroidectomy and cholecystectomy were successfully performed. Removed choleliths were comprised of calcium carbonate and bilirubinate. Histopathological analysis of tissue suggested low grade pancreatic and hepatobiliary disease, as well as hyperthyroidism, might have contributed to stone formation.
