Ectopic parathyroid glands tend to be located in positions defined by their embryologic path during fetal development. We describe such a case of primary hyperparathyroidism due ectopic retropharyngeal adenoma (PTA) teenage girl with mild symptomatology. The initial workup scintigraphy showed suspicious uptake above the level thyroid gland, ultrasound, and computed tomography failed localize an adenoma. Magnetic resonance imaging precisely localized PTA, which led successful surgical removal.
