Summary A one‐year‐old female trotter was examined for an enlarging mass on the proximoventral aspect on the right side of the proximal cervical area. On clinical and ultrasonographic examination the mass was found to be a fluid filled cavity of approximately 8 cm in diameter surrounded by a capsule. The right lobe of the thyroid gland was closely related to the mass. The mass and the right thyroid gland were surgically excised. Histological examination revealed an ultimobranchial cyst. This is the first description of the diagnosis and treatment of a thyroid cystic abnormality related to the fifth branchial pouch (ultimobranchial body) in a horse.
