Hypercalcemia in a patient with tuberculous adrenal insufficiency.

OBJECTIVES

To raise awareness of hypercalcemia as a rare and at times inaugural manifestation of adrenal insufficiency.

CASE REPORT: Evaluation of hypercalcemia in a 43-year-old man showed adrenal insufficiency. Biopsies of the testes and adrenal glands revealed epithelioid and giant cell lesions indicating tuberculosis. Although tuberculosis can contribute to hypercalcemia, this possibility was ruled out in our patient by the low serum 1,25-dihydroxy-vitamin D3 levels and return to normal of serum calcium and renal function under hormone replacement therapy. It should be noted, however, that a course of pamidronate was given.

CONCLUSION

The mechanism of hypercalcemia associated with adrenal insufficiency is controversial. Hyperparathyroidism was ruled out in our patient. Adrenal insufficiency should be considered in some patients with hypercalcemia.
