Abstract

The most common manifestation of multiple endocrine neoplasia type 1 (MEN1) is hyperparathyroidism. Treatment of hyperparathyroidism in MEN patients is surgical removal of the parathyroid glands, however ectopic parathyroid gland is challenging for treatment. A 51-year-old female, the eldest of 3 MEN1 sisters, had hyperparathyroidism with ectopic parathyroid adenoma in the mediastinal para-aortic region, which was detected by technetium-99m (Tc-99m) sestamibi scintigraphy and single-photon emission computed tomography/computed tomography (SPECT/CT). She underwent total parathyroidectomy with video-assisted thoracoscopic surgery on an anterior mediastinal mass. Anterior mediastinal parathyroid adenoma in MEN1 patients is rare. Precise localization of an ectopic parathyroid gland with Tc-99m sestamibi SPECT/CT can lead to successful treatment of hyperparathyroidism. This is the first reported case in the literature of mediastinal parathyroid adenoma in MEN1 patient visualized by Tc-99m sestamibi SPECT/CT.
