Introduction. This is an extremely rare case of a patient with metastatic follicular thyroid cancer who continued to produce thyroid hormone and was iodine scan positive without stimulation after thyroidectomy and radioiodine (I-131) therapy. Patient Findings. A 76-year-old Caucasian male was diagnosed with metastatic follicular thyroid carcinoma on lung nodule biopsy. Total thyroidectomy was p...

UNLABELLED BACKGROUND/MATERIAL AND METHODS: The aim of this study was to assess the reliability of radioiodine ((131)I) and a gamma probe for radio-guided surgery (RGS) to detect and radically dissect lymph node recurrence (LNR) in 15 patients with differentiated thyroid cancer (DTC). The major inclusion criterion was the presence of a radioiodine-positive LNR after previous total thyroidectomy...

BACKGROUND Follicular cell thyroid carcinoma is a quite aggressive form of thyroid cancer. About 10% of follicular thyroid carcinoma shows multiple metastases: lung and bone are the most common sites of metastasis. Renal involvement from thyroid primary cancer is very rare with incidence of 4.5%-5.9%. PURPOSE We report the first laparoscopic conservative treatment of renal metastasis from thy...

RATIONALE The spine is the most common site of bone metastases due to thyroid cancer; however, spinal cord compression as a complication of metastatic thyroid cancer is very rare. PATIENT CONCERNS A 48-year-old female patient was presented to the Neurosurgical Department, complaining of progressive back neck pain with bilateral upper extremities numbness and weakness for 4 months. DIAGNOSIS...

Radioiodine whole body scan (WBS), related to sodium iodide symporter (NIS) function, is widely used to detect recurrence/metastasis in postoperative patients with thyroid cancer. However, the normal thymic uptake of radioiodine has occasionally been observed in young patients. We evaluated the expression of thyroid-related genes and proteins in the human thymus. Thymic tissues were obtained fr...

BACKGROUND Radioactive iodine is commonly administered following thyroidectomy for differentiated thyroid carcinoma to ablate the thyroid remnant. The optimal administered activity of radioiodine is unknown. METHODOLOGY/PRINCIPAL FINDINGS Adult subjects (n = 160) diagnosed with papillary or follicular thyroid carcinoma were randomly allocated to receive either 1100 MBq (30 mCi) or 3700 MBq (1...

Molecular imaging plays an important role in the evaluation and management of thyroid cancer. The routine use of thyroid scanning in all thyroid nodules is no longer recommended by many authorities. In the initial work-up of a thyroid nodule, radioiodine imaging can be particularly helpful when the thyroid stimulating hormone level is low and an autonomously functioning nodule is suspected. Rad...

BACKGROUND Mazabraud's syndrome is defined as the association between fibrous dysplasia and intramuscular myxomas. The syndrome was first described in 1967 and, up until now, less than 100 cases have been reported worldwide. Here we report the association between this rare syndrome and thyroid cancer. When a malignant disease occurs in a patient affected by this syndrome, the differential diagn...

hyperthyroidism is a common disease and one of the best methods for its treatment is radioiodine therapy. treatment with antithyroid drugs brings patients to euthyroidism before radioiodine therapy. antithyroid drugs should be discontinued before radioiodine therapy to increase thyroid uptake. the purpose of this study was to determine the optimal time of methimazole (mtz) discontinuation. one ...
