title: Nasal secretion of iodine-131.
abstract: A case of total-body I-131 imaging showing an abnormal collection of I-131 is presented. The site of uptake was initially thought to be a thyroid carcinoma metastasis in the upper right thigh but was subsequently shown to be due to the nasal secretion of I-131 contaminating a handkerchief. Other possible causes of I-131 contaminated handkerchiefs are also discussed.
