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.
