Excision of a parathyroid adenoma of the aorto-pulmonary window under thoracoscopy

OBJECTIVES: Neck exploration is usually required in all cases of primary hyperparathyroidism. Without a precise localization preoperatively cervicotomy may be unsuccessful, especially in case of an ectopic adenoma. CASE REPORT: A patient with primary hyperparathyroidism due to a solitary adenoma localized in the middle mediastinum was identified on preoperative computed tomography and technetium-99m-sestamibi radionuclide scan. The tumor was successfully removed at thoracoscopy without neck exploration. DISCUSSION: Preoperative localization of primary hyperparathyroid tumors is not indicated in all patients. In some selected cases (acute hypercalcemia, reoperation, serious illness) prior neck exploration would be useful in guiding the surgeon.
