Annals of Thoracic and Cardiovascular Surgery
Parathyroid cysts rarely cause hyperparathyroidism. In addition, they rarely occur in the thymus. We report a 56-year-old woman with hypertension on telmisartan and hydrochlorothiazide, who developed symptomatic hypercalcemia for a month. Initial serum calcium was 15.6 mg/dL, together with inappropriately elevated intact PTH at 437 pg/mL. Coincidentally, an anterior mediastinal mass on chest imaging was found.
