Parathyroid Adenoma

History: 50 year old female with a history of hypercalcemia.

Parathyroid adenoma: Tc-99m-Sestamibi scan showing a focus of increased radiotracer activity in the region of the inferior right thyroid gland, both on the immediate images and the 2 hour delayed images. This is compatible with a parathyroid adenoma, given the history of hypercalcemia.

The patient went on to receive a CT scan of the neck with contrast which revealed an enhancing nodule posterior to the inferior right thyroid lobe, which was excised and confirmed on pathology to be a parathyroid adenoma. Hyperparathyroidism was the etiology of the patient’s hypercalcemia.
