A 52-year-old woman noticed a painless neck mass moving with deglutition for 1 month. Ultrasonography demonstrated a non-echogenic cystic mass corresponding to the finding from the 99mTc-sestamibi SPECT/CT study (Fig. 1). Fine needle aspiration showed colorless fluid, which its analysis showed an elevated parathyroid hormone (PTH) level of 611.9pg/mL and undetectable thyroglobulin. Functioning parathyroid cyst was diagnosed with the presence of hypercalcemia (serum calcium 11.5mg/dL) and elevated serum PTH (111pg/mL; 15–65). Surgical removal was performed with the pathological examination consistent with a cystic degeneration of parathyroid adenoma. Post-operatively, her primary hyperparathyroidism and hypercalcemia have been resolved.
