Abstract:

Parathyroid adenomas are the most important cause of primary hyperparathyroidism. The diagnosis of primary hyperparathyroidism is established based on the combination of elevated serum calcium and parathyroid hormone levels. Parathyroid adenomas are rarely found in the mediastinum. The definitive treatment of primary hyperparathyroidism is parathyroidectomy. The parathyroid hormone and serum calcium levels were determined high in a fifty-seven-year-old female patient with a history of bone and abdominal pain, fatigue, and kidney stones. Anterior mediastinal ectopic parathyroid adenoma was detected with Technetium-99m (Tc-99m) methoxy isobutyl isonitrile scintigraphy. Adenoma was removed surgically with partial median sternotomy. Serum calcium and parathyroid hormone levels returned to normal on the 3rd postoperative day. The patient was discharged with healing.
