4. Conclusions
Parathyroid lipoadenoma is a rare cause of primary hyperparathyroidism, which is mainly manifested as infiltration of a large amount of adipose tissue in the gland, and due to excessive fat content, its sensitivity in imaging localization diagnosis is reduced, and the difficulty of parathyroid lipoadenoma is still in preoperative localization diagnosis, so we believe that parathyroid lipoadenoma needs to rely on paraffin pathology to make a final diagnosis.This case report serves as a reminder that patients with preoperative unprovoked primary hyperparathyroidism and negative imaging findings may have a parathyroid lipoadenoma. During intraoperative thyroidectomy or lymph node dissection, it is important to carefully examine the adipose tissue for the possibility of parathyroid lipoadenoma, as this can lead to postoperative hypoparathyroidism or even intractable hypocalcemia.
