IntroductIon Ectopically located hyperfunctioning parathyroid gland(s) are responsible for approximately 6–16% of hyperparathyroidism cases, in which about 6% can be ascribed to ectopic growth in the mediastinal site.[1] Treatment of ectopic adenomas usually requires resection. There are various techniques to resect ectopic parathyroid glands, which are mainly depended on the ectopic gland’s location. However, choosing the correct type of treatment for cases can be difficult since there are no commonly accepted guidelines for treatment selection.
