Özet
Nonphysiologic I-131 uptake detected on images is usually interpreted as suggesting functioning thyroid metastases. However, extrathyroidal I-131 accumulation does not always imply thyroid cancer metastases and has been reported on many occasions, including various nonthyroidal neoplasms and contamination by body secretions. To avoid unnecessary therapeutic interventions, it is extremely important to distinguish properly false-positive sites of I-131 localization. The authors report 2 examples of unusual false-positive I-131 whole-body scans in papillary thyroid carcinoma caused by chronic sialadenitis of a submandibular gland and a maxillary mucous retention cyst. False-positive uptake and contamination sources were elucidated by careful examination of the patients and further imaging studies.
