Supernumerary ectopic parathyroid adenoma in the aortopulmonary window: Navigating diagnostic and surgical challenges

This case highlights the challenges of diagnosing ectopic parathyroid adenomas and the importance of considering rare ectopic adenomas in patients with PHPT, particularly when standard imaging doesn't yield conclusive results. We also discuss the role of advanced imaging modalities and intraoperative PTH monitoring in guiding surgical decisions and determining the appropriate point to conclude the procedure, ensuring successful outcomes.
