False-positive results are due to TI-201 accumulation. Some known causes are thyroid carcinoma, adenomatous goiter, chronic thyroiditis, and lymph node involvement of certain diseases. The authors report a case of brown tumor and pathologic bone fracture, which might be potential causes of false-positive TI-201-Tc-99m subtraction imaging. © Lippincott-Raven Publishers.
