Nasal Secretion of lodine-131

Diffuse 131I Lung Uptake in Bronchiectasis: A Potential Pitfall in the Follow-Up of Differentiated Thyroid Carcinoma

“…This is the case for contamination artifacts due to physiological secretions (16)(17)(18), such as saliva, nasal secretions, sweat, urine, and vomitus.…”

“Hidden” bone metastasis from thyroid carcinoma: A clinical note

“…The normal patterns of radioiodine uptake in the nose, mouth, and salivary (parotid and submandibular) glands have been described and although there may be some differences due to pre-existing abnormalities and variation in uptake, the usual pattern includes focal nose and linear buccal mucosa activity. 7 In the present case, the clue to the abnormality was the more intense activity in the posterior image whereas nose, mouth and salivary glands are located anteriorly with their activity being more prominent and often only visible in the anterior image. As originally reviewed, this patient’s study was in fact a “false” false negative.…”

Nasal Symptoms After Radioiodine Therapy: A Rarely Described Side Effect with Similar Frequency to Lacrimal Dysfunction

“…In addition to RAI uptake within the area of the nose itself (13,14,38), uptake due to RAI contamination of nasal secretions had been described in a nose ring (39) and handkerchiefs retained in pockets (40,41). In this sense, nasal uptake could be likened to many of the other causes of iodine uptake visualized on whole body scanning that does not indicate residual or recurrent thyroid cancer.…”
