Ectopic Mediastinal Parathyroid Adenomas: Diagnostic and Therapeutic Challenges Through a Series of Three Cases

Abstract Ectopic mediastinal parathyroid adenoma is a significant cause of refractory and recurrent primary hyperparathyroidism. Although rare compared to cervical locations, this pathology presents particular diagnostic and therapeutic challenges. We report a series of three cases illustrating these difficulties, along with favorable outcomes achieved through advanced imaging and appropriate surgical management. An updated literature review is provided to better understand the optimal care for these patients.
