title: Importance of intraoperative parathyroid hormone measurement in the diagnosis of parathyroid lipoadenoma.
abstract: BACKGROUND
  Parathyroid lipoadenoma is an uncommon tumor that may be difficult to diagnose on intraoperative frozen section. Intraoperative parathyroid hormone (PTH) measurement is useful in assessing the adequacy of parathyroidectomy. This case demonstrates the value of intraoperative PTH measurement in recognizing a parathyroid lipoadenoma.
  
  
  RESULTS
  A case of a 62-year-old woman with primary hyperparathyroidism in which intraoperative PTH measurement helped confirm the diagnosis of parathyroid lipoadenoma is presented.
  
  
  CONCLUSIONS
  In patients with primary hyperparathyroidism, a significant decrease in intraoperative PTH confirms that an enlarged parathyroid with normal to low cellularity containing abundant fat is a lipoadenoma and that further exploration is not necessary.
