title: Successful repeat transcatheter ablation of a mediastinal parathyroid adenoma 6 years after alcohol embolization.
abstract: Recurrent hyperparathyroidism is rare following transcatheter ablation of mediastinal parathyroid adenomas. When it occurs it is usually early and resistant to further attempts at ablation. We present a patient with primary hyperparathyroidism in whom two surgical attempts at cure had been unsuccessful. Subsequently, a mediastinal adenoma was demonstrated angiographically and embolized with absolute alcohol. Hyperparathyroidism recurred 6 years later and the mediastinal adenoma was subsequently successfully ablated a second time by angiographic embolization with ionic contrast medium.
