Unexpected radioiodine distributions may be encountered on post-therapy I-131 thyroid cancer scans due to a range of benign physiological processes, causing diagnostic dilemma and potentially mimicking metastatic disease. We present two cases of intense focal uptake related to concentration of radioiodine activity on wrist-watches by differing mechanisms, which should be confirmed by clinical history and not be mistaken for metastatic disease.
