ABSTRACT

We report a 77 years old woman with osteoporosis in whom a hyperparathyroidism secondary vitaminD deficiency and renal hypercalciuria was diagnosed. Serum calcium was normal. During the diagnostic work up, a parathyroid nodule was discovered and subjected to a fine needle aspiration biopsy, that showed normal parathyroid cells. The patient was treated with calcitriol, cholecalciferol, hydrochlorothiazide and intravenous zolendronic acid. There was a reduction in urinary calcium and serum PTH levels and improvement of serum 25 hydroxy vitamin D levels.
