2. ENDOCRINOLOGY

There are an increasing number of conditions that lead to false-positive I-131 whole-body scans, with serious consequences in differentiated thyroid cancer management. They are classified in five main groups, according to mechanism: elimination of iodine in body fluids, inflammation and infection, transudates and cysts, nonthyroid neoplasms, and miscellaneous, discussed by the authors, who present their own experience, including tooth inflammation (5 patients), inflammation on the nose (hot nose), and parotid gland duct ectasia. The last is the first one reported on the medical literature. The demonstration of the false-positive nature of the findings avoided unnecessary I-131 treatment. Appropriate steps to disclose spurious cases are exposed.
