a 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with loomci of iodine-131 and negative whole body scans was referred for follow up study. tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. the patient was operated, the parathyroid adenoma was removed. in thi...

A 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with lOOmCi of iodine-131 and negative whole body scans was referred for follow up study. Tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. The patient was operated, the parathyroid adenoma was removed. ...

Whole body iodine-131 scan is a well-established imaging method for the detection of metastatic or residual tumor sites in patients with well-differentiated thyroid cancer. Many false-positive iodine-131 scan findings mimicking metastatic thyroid cancer have long been reported. The authors describe a false positive uptake in normal gallbladder on post-ablative iodine-131 scan in a patient with ...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...

PURPOSE To determine whether the selective BRAF inhibitor, dabrafenib, can stimulate radioiodine uptake in BRAF V600E-mutated unresectable or metastatic iodine-refractory papillary thyroid cancer (PTC). EXPERIMENTAL DESIGN Ten patients with BRAF V600E-mutant iodine-refractory PTC were enrolled. Absence of radioiodine uptake on iodine-131 whole body scan obtained within 14 months of study entr...

We report a very rare case of incidental intrapericardial thyroid in a papillary thyroid cancer patient. Post ablation scan revealed iodine-131 (131I) uptake in the mid-chest. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was performed and showed a 18F-FDG avid lesion between the right atrium and the ascending aorta, (which was) shown to be an ...

BACKGROUND Low iodine diet (LID) is recommended in patients with differentiated thyroid cancer before radioiodine administration. Patients with increased thyroglobulin (Tg) level, but negative (131)I whole body scan present diagnostic and therapeutic dilemma. This study was designed to evaluate the benefit of a two-week LID in patients with elevated serum Tg levels and negative (131)I whole bod...

Aim: Differentiated thyroid carcinoma has a favorable prognosis, even in the presence of distant metastases, if the tumor cells are able to concentrate radioiodine. Nonetheless, up to 30% of thyroid cancer patients with elevated serum thyroglobulin (Tg) and negative radioiodine whole-body scan findings represent a diagnostic dilemma. In this study we assessed the diagnostic contribution of anat...

OBJECTIVE Fluorodeoxyglucose positron emission tomography/computed tomography imaging in the follow-up of patients with differentiated thyroid carcinoma who have high serum thyroglobulin, negative iodine-131 whole body scan and suppressed thyrotropin. PATIENTS AND METHODS A total of 90 patients (31 male and 59 female) with differentiated thyroid carcinoma who have high serum thyroglobulin and...
