Where this comes from

Abstract

A 73-year-old man with papillary thyroid cancer underwent total thyroidectomy and bilateral neck dissections. He was subsequently treated with 131I. The posttherapy scan showed radioiodine uptake at the left supraorbital region, which localized to a metallic surgical clip. There was no evidence of metastasis in this area. This is not a commonly reported finding. Knowledge of this false-positive finding can help avoid unnecessary workup and treatment.
