Background: Ectopic mediastinal parathyroid tumor (EMPT) is a rare cause of primary hyperparathyroidism (PHPT);\nit is difficult to resect using the cervical approach. We describe a case of using video-assisted thoracic surgery\n(VATS) for EMPT resection.\nCase presentation: A 67-year-old woman with a history of postoperative thyroid cancer had no symptoms. She\nwas diagnosed with PHPT and underwent thyroid cancer surgery. She had serum calcium and intact parathyroid\nhormone (PTH) levels of 11.1 mg/dL and 206 pg/mL, respectively. Chest computed tomography showed a 10-mm\nnodule in the anterior mediastinum. Technetium-99m methoxyisobutyl isonitrile scintigraphy showed an abnormal\nuptake lesion in the anterior mediastinum. She was diagnosed with PHPT caused by EMPT and underwent VATS.\nThe pathological examination confirmed parathyroid adenoma. Her serum calcium and intact PTH levels were\nnormal from 15 min after tumor resection. She has had no recurrence of EMPT.\nConclusions: The VATS approach was effective for the resection of EMPT.
