Localization of abnormal parathyroid glands using thallium-201
Ectopically located parathyroid adenomas may be difficult to find during initial neck exploration. They account for over 70 percent of missed adenomas found at reexploration. Preoperative localization of parathyroid adenomas would reduce unnecessary dissection and possibly reduce the number of negative results of initial neck exploration. Before reoperative parathyroid surgery is performed, some means of localization is mandatory to detect ectopic adenomas in the neck and mediastinum. Computed tomography and ultrasonography cannot effectively evaluate the mediastinum. Angiography and venous parathyroid hormone sampling are invasive, costly, and tedious to perform. We have shown that thallium-201 will accurately localize ectopic parathyroid adenomas. All 10 adenomas found in positions not immediately adjacent to the thyroid gland were detected by thallium-201 scintigraphy. One was a mediastinal adenoma resected with a median sternotomy. Our results suggest that thallium-201 scintigraphy should be the initial localization procedure of choice before all reexplorations. Its use before initial explorations, as well, will enable the surgeon to immediately direct attention to the area of the localized adenoma. If mediastinal uptake is found to be present, then median sternotomy may be performed during initial surgery provided a thorough neck exploration is performed first.
