We present a 74-year-old woman with primary hyperparathyroidism, with elevated parathyroid hormone and calcium. Tc-99m-methoxyisobutyl isonitrile (sestamibi) planar imaging showed a focus of uptake over the inferior aspect of the right submandibular gland that was localized on the single-photon emission computed tomography with CT.
