AB A woman with papillary thyroid carcinoma treated with surgery and postoperative 131I returned 4 y later for a whole-body survey. The imaging results initially suggested disease recurrence but were later found to be false positive and due to 131I uptake in a necklace that had been contaminated by the patient’s saliva. This case stresses the importance of having the patient remove all jewelry before undergoing a radioiodine survey.
