Giant mediastinal parathyroid adenoma with hypercalcemia.
Parathyroid disease is uncommon, but when found it is always of interest to the physician. Most patients with parathyroid disease also have hypercalcemia. Benign adenomatous disease is the most frequent surgical parathyroid lesion seen. Most of these lesions occur in the neck and are usually <2 cm in diameter. We report the case of a 50-year-old patient with familial neurofibromatosis, a serum calcium of 19 mg/dl, nephrocalcinosis, and renal failure. Evaluation revealed a large (5.7 x 4.5 x 2.9-cm) mediastinal adenoma. At resection, the tumor weighed 39.5 g. Symptomatology rapidly improved postoperatively.
