Hyperparathyroidism is very rare disorder in childhood. Patients usually present with non-specifi c symptoms such as nausea, vomiting, constipation, irritability, lethargy, headache, polyuria and polydipsia, and the diagnosis can therefore be delayed. Diagnosis is made by clinical examination and laboratory fi ndings. Parathyroid hyperplasia and adenomas can be differentiated with imaging methods. Hypocalciuric hypercalcemia may have similar fi ndings and investigating urine calcium levels is important for the differential diagnosis. Defi nitive treatment of a parathyroid adenoma is removal of the adenoma. End organ damage such as bone changes and nephrocalcinosis should be kept in mind. We discuss a 12-year-old boy who had hypercalcemia due to hyperparathyroidism. He presented at our emergency department because of nausea and vomiting and was diagnosed with a solitary parathyroid adenoma located on the lower right side of the thyroid gland by using parathyroid scintigraphy
