Giant Parathyroid Adenoma Excised through Endoscopic Trans- Axillary Parathyroidectomy; A Case Report with Literature Review
Abstract
Large parathyroid adenomas consist 1.5% of all adenomas. While minimally invasive parathyroidectomy is the method of choice with established advantages, surgeons prefer open surgery for large adenomas to reduce surgical risks. Here, we present a 41-year-old male with primary hyperparathyroidism due to large size parathyroid adenoma (3.2 cm) that was removed successfully by endoscopic trans-axillary parathyroidectomy. This presentation can guide surgeons to choose this minimally invasive technique, even for large adenomas.
