Intrapericardial parathyroid adenoma(†)

Primary hyperparathyroidism from a parathyroid adenoma is common. Ectopic parathyroid glands have been reported in numerous locations, including the chest. We present a single case report of an intrapericardial parathyroid gland found after failed bilateral neck exploration. The patient presented with severe, recurrent nephrolithiasis and acute renal failure prior to his surgical intervention. Repeat imaging identified a parathyroid adenoma in the mediastinum that was localized to the aortopulmonary window. After attempts at minimally invasive thoracotomy and posterolateral thoracotomy, a median sternotomy was ultimately required to identify the adenoma.
