Suspected parathyroid tumours were localised in 12\/14 equids imaged using ultrasonography alone (2\/3), technetium 99m Tc sestamibi scintigraphy alone (1\/1) or both modalities (9\/10). Three horses did not have imaging performed. Surgical exploration successfully excised tumours in six of 10 cases. Five were located at the thoracic inlet, and surgery resulted in complete cure. One tumour was excised from the thyroid lobe, and the horse remained hypercalcemic. Four other cases explored surgically, four treated medically and three that were not treated also remained hypercalcemic.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Main limitations<\/jats:title>\n                    <jats:p>The small study size prohibited statistical analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Parathyroid adenomas in equids can be successfully localised with ultrasonography and scintigraphy.
