He was initially diagnosed with hypercalcemia (serum calcium:3.75mmol/L), hyperparathyroidism (parathyroid hormone < PTH>:739pg/ml = 81.29pmol/L), and thyroid mass at a local hospital, where he received fluid infusion, diuresis, and calcitonin for symptomatic treatment. Here, PTH is linked to hyperparathyroidism.
