Incidentally Visualization of the Thymus on Whole-Body Iodine Scintigraphy
نویسندگان
چکیده
Radioiodine uptake is not commonly seen by the thymus gland. On the contrary, the gland is slowly replaced by fat after puberty. Herein, we present 2 patients with papillary thyroid carcinoma, follicular variant, and cervical lymph node involvement. After total/near-total thyroidectomy, the patients received I for ablation therapy. On posttreatment radioiodine scintigraphy, mediastinal I uptake was noted that finally was histologically/anatomically diagnosed as thymus gland uptake. It should be borne in mind as a potential cause of false-positive whole-body I scintigraphy.

متن کاملCuboid fracture in a toddler discovered on the whole body bone scan: A case report
This report presents a 3.5-year-old boy who was hospitalized for limping. Medical history and physical exams were not suggestive for any definitive diagnosis. Laboratory and radiographic exams did not support any specific diagnosis either. Subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

RATIONALE Post-therapy or diagnostic whole-body radioiodine scintigraphy is widely employed to evaluate the residual, recurrence, or metastases of differentiated thyroid carcinoma because of the high sensitivity and accuracy. However, it has pitfalls. PATIENT CONCERNS We described a 63-year-old male with a history of papillary thyroid carcinoma who was referred for iodine-131 ablation therapy...
متن کاملMultiple non-malignant iodine uptake in a 131I whole body scan of a patient with papillary thyroid carcinoma: Importance of SPECT/CT
After thyroidectomy in papillary thyroid carcinoma (PTC) patients, whole body radioiodine scan (WBIS) is necessary for localization of any abnormal radioiodine avid lesions. However false-positive radioiodine uptake in WBIS can be problematic. We report a 32 years old female patient with PTC. After thyroidectomy and radioiodine therapy WBIS was performed. In her post therapy WBIS, there were zo...
متن کاملDetection of solitary bone metastasis by 99mTc-octreotide scintigraphy in a patient with Hurthle cell carcinoma: A case report
A 75-year-old male patient with non-avid radioiodine Hurthle cell carcinoma was evaluated by 99m Tc- octreotide scintigraphy, in order to find possible metastatic lesions. A bony metastatic lesion was detected by this procedure which was confirmed by histopathology.99mTc-octreotide scintigraphy is a precise and cost-effective imaging modality for detection of non-iodine av...
