Abstract:
Radioactive iodine treatment is useful for ablating remnant thyroid tissue and metastasis of well-differentiated thyroid cancer with long-lasting effects. A scintigraphy after radioactive iodine treatment is a major imaging modality for detecting metastasis and assessing the management of metastasis. However, caution is required when reading the scan due to potential false-positive findings. In this study, scintigraphy and single-photon emission computed tomography/computed tomography images after radioactive iodine treatment revealed a physiological uptake of radioactive iodine due to lacrimal secretion around an artificial eyeball; such findings have not been reported previously.
