Hypercalcemic crisis caused by a parathyroid adenoma with hemorrhage and cystic degeneration: A case report / 中华内分泌代谢杂志

This paper reported a rare case of hypercalcemic crisis caused by a parathyroid adenoma with hemorrhage and cystic degeneration. Preoperative imaging examination of the patient was unable to determine the histological origin of the cervical cystic lesion. Despite aggressive medical treatment and hemodialysis, hypercalcemic crisis could not be relieved. Therefore, surgical exploration and excision of the cervical lesion were performed, and final diagnosis of parathyroid adenoma with hemorrhage and cystic degeneration was confirmed by pathology. Blood calcium level and renal function returned to normal after the surgery.
