Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...

Introduction: Thyroid hormones play an important role in the regulation of metabolism, maturity and reproduction. Thyroid dysfunction affects almost all endocrine glands such as pituitary and testis. The aim of this study was to investigate alterations of testosterone and luteinizing hormone (LH) serum levels as well as weights of thyroid gland and testes in methimazole (MMI)-induced hypothy...

metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. metastasis from thyroid gland is extremely rare to oral region. we present an unusual case of metastatic follicular carcinoma of thyroid in max...

background  it is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. the aim of this study was to evaluate the entrance surface dose (esd) of pediatric chest radiography compared to the diagnostic reference levels (drl) and evaluation the efficacy of the lead (pb)...

An ectopic location of the thyroid gland usually occurs in the midline, starting anywhere from the tongue to the diaphragm. The occurrence of an ectopic thyroid gland in a non-midline site is extremely rare. We report a 32-year-old Malay woman with an aberrant thyroid gland presenting as a parapharyngeal lesion. She had a normally functioning thyroid gland. An ectopic thyroid should be consider...

It is not uncommon to encounter variations in the Thyroid gland during surgeries. Complete detailed anatomical variations in arterial and venous supply including the presence of ectopic glands is useful for diagnosis and prognosis of patients involved with thyroid disorders. With these facts we tried to evaluate the Anatomical and Morphological variations of the thyroid gland. The study was con...

The external branch of the superior laryngeal nerve (ELN) is intimately associated with the superior thyroid artery (STA) in relation to the superior pole of the thyroid gland, rendering it vulnerable to injury during the ligation of this vessel during thyroidectomy. Although most texts acknowledge the fact that the nerve is in close relation to the STA, there has not been an anatomical study t...

Goiters (from the Latin guttur, throat) have been known since 2700 b.c., long before the thyroid gland was recognized. The thyroid gland was first documented by the Italians of the Renaissance period. Leonardo da Vinci originally depicted the thyroid in his drawings as two separate glands on either side of the larynx. The term thyroid gland (Greek thyreoeides, shield-shaped) is attributed to Th...
