Pediatric hyperparathyroidism and ossification of the ligamentum flavum: A case report.

Hyperparathyroidism (HPT) is a rare endocrine disorder in the pediatric population. Patients often present with bone pain and abnormal gait along with biochemical findings of hypercalcemia, hypophosphatemia, and elevated parathyroid hormone (PTH). HPT is most commonly due to the unregulated secretion of PTH from a parathyroid adenoma. Diagnosis is usually identified with sonography and scintigraphy to localize parathyroid anomalies. Treatment traditionally involves parathyroidectomy with postoperative monitoring of serum calcium and phosphate levels. Here we present a case of a preadolescent girl with metabolic bone disease secondary to hyperparathyroidism.
