False-positive uptake on radioiodine whole-body scintigraphy: physiologic and pathologic variants unrelated to thyroid cancer.
Radioiodine whole-body scintigraphy (WBS), which takes advantage of the high avidity of radioiodine in the functioning thyroid tissues, has been used for detection of differentiated thyroid cancer. Radioiodine is a sensitive marker for detection of thyroid cancer; however, radioiodine uptake is not specific for thyroid tissue. It can also be seen in healthy tissue, including thymus, breast, liv...
متن کاملPhysiologic and False Positive Pathologic Uptakes on Radioiodine Whole Body Scan
A radioiodine whole body scan relies on the fact that differentiated thyroid cancer is more efficient at trapping circulating radioiodine than any other tissues.(Hyer, Newbold et al. 2010) Therefore, when I-131 is administered it accumulates in the thyroid cancer tissues and a radioiodine whole body scan plays an important role in the management of patients with differentiated thyroid cancer. U...
متن کاملRadioiodine avid adenomatous colon polyp in a post-treatment whole body radioiodine scan
A 47 year old female with papillary thyroid carcinoma was referred to our department for post-treatment whole body iodine scanning. The acquired images revealed a focal zone of intense radiotracer uptake in the right lower quadrant of the abdomen. SPECT/CT fused slices showed a focal zone of the radioiodine (131I) uptake in the right colon wall. Colonoscopy revealed a pedunculated po...
متن کاملExtremity Radioactive Iodine Uptake on Post-therapeutic Whole Body Scan in Patients with Differentiated Thyroid Cancer
Objective(s): We investigated a frequency of lower extremity uptake on the radioactive iodine (RAI) whole body scan (WBS) after RAI treatment in patients with differentiated thyroid cancer, in order to retrospectively examine whether or not the frequency was pathological. Methods: This retrospective study included 170 patients with thyroid cancer, undergoing RAI treatment. Overall, 99r (58%) an...
متن کاملUnusual false-positive results of whole-body 131I scintigraphy: Four different case scenarios
Post-treatment or diagnostic whole-body radioiodine scintigraphy is widely used to assess the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy that this assessment provides. While bearing in mind all the diagnostic potential of this test, we have to consider its’ potential pitfalls, as well. Herein, we present 4 patients with d...
