A Case of Canine Thyroid Adenoma

Abstract

A neutered male miniature dachshund aged 10 years and one month presented to the hospital with a soft mass on the left side of the neck. A thyroid tumor was suspected by ultrasonography, and this was confirmed by computed tomography (CT) examination. Thyroidectomy was subsequently performed, and thyroid adenoma was diagnosed based on histopathological examination. Although thyroid adenoma is rare in dogs, CT examination may be useful in differentiating thyroid adenoma from thyroid cancer.
