BACKGROUND In addition to its established role in oncologic imaging, F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) is useful for the assessment of inflammatory activity. However, subacute thyroiditis (SAT) in thyrotoxicosis is rarely detected during these scans. CASE A 66-year-old man with SAT in thyrotoxicosis demonstrated symptoms of transient fatigue,...

The sodium/iodide symporter (NIS) mediates iodide uptake in the thyroid gland and lactating breast. NIS mRNA and protein expression are detected in most thyroid cancer specimens, although functional iodide uptake is usually reduced resulting in the characteristic finding of a 'cold' or non-functioning lesion on a radioiodine image. Iodide uptake after thyroid stimulating hormone (TSH) stimulati...

Thyroiditis is a general term that encompasses several clinical disorders characterized by inflammation of the thyroid gland. The most common is Hashimoto thyroiditis; patients typically present with a nontender goiter, hypothyroidism, and an elevated thyroid peroxidase antibody level. Treatment with levothyroxine ameliorates the hypothyroidism and may reduce goiter size. Postpartum thyroiditis...

background: the therapeutic administration of 131i for thyroid remnant ablation and for metastases comes up with some adverse effects. this study was conducted to investigate whether single high dose radioiodine therapy affects lacrimal gland functions or not. materials and methods: seventy-eight eyes of 39 patients, who were diagnosed as differentiated thyroid carcinoma, were objectively teste...

Introduction: 18F-Choline PET-CT is an increasingly used technique in patients with prostate cancer. The main indication is to localise the disease in patients with biochemical recurrence. To accurately interpret 18F-Choline PET, knowledge of normal tracer distribution is paramount. The aim of this study was to describe the normal distribution pattern of 18F-Cho...

To the Editor: Lingual thyroid is a rare embryological anomaly caused by failure of the gland to descend from the foramen cecum to its normal site in the pre-laryngeal area. Its precise pathogenesis is u...

Although tuberculosis involves every organ and has a wide range of clinical manifestation, however involvement of the thyroid gland is rare. We report a case of a 25-yr-old female with supraclavicular lymphadenitis that developed nodular swelling of the thyroid and had symptoms and sonographic features mimicking a nodule with a cystic component. The diagnosis was made by using fine needle aspir...

introduction: congenital hypothyroidism (ch) is one of the most common preventable causes of mental retardation. its worldwide incidence is estimated to be one in 2500-5500 births. assessment of thyroid gland in neonates is critical. the aims of this study were to demonstrate the incidence of ch in neonates born in yazd province, iran in 1389 (2010) and compare the results with other reported s...
