Scintigraphic and single photon emission computed tomography (SPECT-CT) findings were reported as parathyroid adenoma just inferior to the lower pole of the right thyroid lobe, possibly involving the right inferior group of parathyroid glands or ectopic adenoma. Further workup revealed severe hypercalcemia (14.5 mg /dl) and markedly raised parathyroid hormone (PTH) levels of 2810 pg/ml (Table 1). This evidence concerns the gene PTH and Hypercalcemia.
