Technetium 99 m-Sestamibi Parathyroid Scan showing a Left Inferior Parathyroid Adenoma
This patient presented with hypercalcemia. A Technetium 99m-Sestamibi Scan was done. Fifteen minutes after the administration of the radioisotope, uptake is visible in the thyroid gland. Two hours later, the uptake is concentrated in the left inferior parathyroid adenoma, after it has "washed off" from the thyroid gland. This study is very important in localizing the parathyroid adenoma prior to minimally-invasive radioguided parathyroidectomy (MIRP) and
