Causes of failure of Tc-99 sestamibi to visualise parathyroid adenoma
In summary this case demonstrates coexistence of parathyroid adenoma and unrecognized thyroid cancer and the necessity to evaluate the thyroid gland prior to parathyroid gland surgery. Most importantly Tc-99m MIBI scans valuable in preoperative localization of parathyroid adenoma and less useful for detecting parathyroid hyperplasia. In recurrent or resistant hyperparathyroidism considering cross sectional imaging such as MRI with or without repeated Tc-99m MIBI scan is helpful in localizing parathyroid adenoma or hyperplasia.
