Case Discussion

As part of her work-up, a blood investigation reveals a high calcium level of 13 mg/dl, a parathyroid hormone level of 450 pg/ml, and the delayed images of the Tc-99m sestamibi scan (not uploaded) showed complete tracer washout from both thyroid lobes with focal tracer retention at the site of the right lower parathyroid gland suggesting right sided parathyroid adenoma.
