Background:
In patients with sporadic primary hyperparathyroidism, preoperative localization studies may discover a solitary mediastinal parathyroid adenoma. In this circumstance a 1-gland mediastinal exploration, either cervical or thoracoscopic, may be curative.
Methods:
In an 18-month period, 5 of 120 consecutive patients underwent an initial 1-gland mediastinal exploration for a solitary mediastinal parathyroid adenoma and 2 patients had a 1-gland mediastinal exploration for persistent hyperparathyroidism. Clinical presentation, imaging studies, surgical techniques, and outcomes were reviewed.
Results:
Sestamibi scans showed a mediastinal parathyroid adenoma in all 7 patients. Computed tomography provided anatomic localization of middle mediastinal parathyroid adenomas. A cervical approach was used in 4 patients who had a superior mediastinal parathyroid adenoma. Thoracoscopic excision was performed in 3 patients with a middle mediastinal parathyroid adenoma. No complications occurred. Calcium and parathyroid hormone levels normalized in all patients.
Conclusions:
Sporadic primary hyperparathyroidism caused by a solitary mediastinal parathyroid adenoma can be treated successfully with 1-gland mediastinal exploration either by a cervical or a thoracoscopic approach as indicated by localization imaging.
