Perioperative Clinical Features of Mediastinal Parathyroid Adenoma: A Case Series

Rare ectopic mediastinal parathyroid adenoma can result in persistent or recurrent hyperparathyroidism. In this article, we summarized the perioperative outcomes of six patients with mediastinal parathyroid adenoma. All patients underwent minimally invasive surgery (MIS). Abnormal accumulation of sestamibi was observed in four of five patients for preoperative localization of adenoma. Postoperatively, the blood calcium dropped quickly. In addition, we found adenoma function was negatively related to adenoma volume in these patients. In conclusion, although MIS is feasible for parathyroid adenoma, blood calcium should be monitored in a timely manner to avoid hypocalcemia postoperatively. In addition, sestamibi might be a potential pitfall when locating parathyroid adenoma.
