Abstract:
The primary hyperparathyroidism (PHPT) is a result of high levels of parathyroid hormone and serum calcium, the most frequent cause is a solitary parathyroid adenoma. Double parathyroid adenoma is <5% of the PHPT. Intrathyroidal parathyroid adenoma (IPA) occurs< 3.2%. We present a case of 58-year-old female with persistent primary hyperparathyroidism due to a second undetected IPA, suspected by ultrasound and confirmed by 99mTc sestamibi single-photon emission computed tomography/computed tomography.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
