Radionuclide parathyroid scans are incomplete when limited to the neck, often missing ectopic mediastinal glands. Including the thorax in scans improves localization accuracy for hyperparathyroidism patients.

Area of Science:

  • Nuclear medicine
  • Endocrinology
  • Surgical anatomy

Background:

  • Radionuclide parathyroid scans are standard for localizing abnormal parathyroid glands, particularly ectopic ones.
  • Ectopic parathyroid glands are frequently found in the mediastinum.

Observation:

  • A survey of 72 regional hospitals revealed that only 25% of the 51 performing parathyroid scans routinely included the mediastinum and chest.
  • At our institution, over a 9-year period, 480 scans were performed, identifying 26 mediastinal parathyroid glands through routine neck and chest imaging.

Findings:

  • Limiting parathyroid scans to the neck results in missed mediastinal glands in approximately 5% of hyperparathyroidism cases.
  • Most identified mediastinal glands were accessible via cervical incision, but some required thoracotomy or thoracoscopy.

Implications:

  • Incomplete parathyroid scanning (neck only) increases the likelihood of surgical exploration failure.
  • Failure to scan the thorax can lead to increased patient morbidity due to missed ectopic glands and potentially more invasive surgical procedures.
