ABSTRACT
Although primary hyperparathyroidism has rarely been described in pediatric patients, prompt diagnosis can avoid severe CNS and metabolic consequences. The aim of this paper is to report a 6 year-old girl whose first symptoms began at eight days of age with cyanosis, hypotonia, and upward gaze deviation. At 4 months, she was admitted due to neurologic disorders and recurrent infection, but the definite diagnosis was made only six years later. Her serum calcium levels are among the highest ever reported in the medical literature, reaching 25.5 mg/dl (6.36 mmol/l). Hypercalcemia, very high levels of parathormone (1550 ng/l--normal range 10-65) and bone deformities posed no problem to diagnosis when she first came to our attention. Nephrocalcinosis and impaired renal function were detected and this child had to be treated with diuretics (furosemide) and hydration that were able to lower her serum calcium levels. Imaging studies including 99mTc-sestamibi scan were not diagnostic. At surgery, the four parathyroid glands were mildly enlarged, with primary hyperplasia. The four glands were removed, cryopreserved, and 14 fragments (1 mm each) were autotransplanted to the braquioradial muscle of the left forearm. After a first phase of hypocalcemia (hungry-bone syndrome), treated with calcium and calcitriol, the calcium levels stabilized. The question is whether she will experience some degree of recovery from her neurological problems, since her severely high calcium levels have been maintained for such a long time.
