Abstract
A 52-year-old woman had mild hypercalcemia (maximum serum calcium level, 2.8 mmol/l; normal range, 2.1 to 2.6 mmol/l) with a mildly elevated serum parathyroid hormone level (73 ng/l; normal range, 12 to 72 ng/l). Parathyroid imaging performed to localize a presumed adenoma showed definite localization to the right side. At surgery, several large lymph nodes were found below the right lobe of the thyroid along the tracheoesophageal groove, and pathologic evaluation of one excised node indicated reactive lymph node hyperplasia. Subsequently, all four parathyroid glands were studied and found to be normal. On follow-up, the patient became normocalcemic. The results of repeated scanning performed 2 months after operation were normal. Although false-positive lymph node uptake has previously been described with subtraction techniques, this is the first time that reactive lymph nodes have been reported to show sestamibi retention with the double-phase technique.
