Computed tomography of the thyroid attenuation (80–100 Hounsfield Units). The presence of thyroiditis can be suggested by a diffusely enlarged and hypo-attenuating (around 45 Hounsfield Units) thyroid gland. This is probably due to follicular cell destruction and reduced thyroid iodine concentration. Marked homogenous enhancement is typically expected. Therefore, moderate thyroid enhancement in a case of thyroiditis suggests a diffuse inflammatory process. It is essential to clinically correlate this with a thyroid function test and serum autoantibody levels. During embryogenesis, the bi-lobed thyroid migrates inferiorly from the foramen cecum of the tongue to the lower neck. Initially, the thyroid primordium passes anterior to the primordial hyoid
Computed tomography of the thyroid enlargement, and calcifications. Management of ITNs depends on several factors including nodule size, patient’s age, overall health status, and the presence or absence of suspicious features such as lymphadenopathy and/or invasion of adjacent structures. A CT scan provides additional important information regarding the local extension of cancer or presence of mass effect, and is useful in evaluating recurrent disease. Furthermore, CT examination plays a crucial role in preoperative evaluation and preoperative surgical planning for patients with symptomatic goiter. Computed tomography of the thyroid In CT scan of the thyroid, focal and diffuse thyroid abnormalities are commonly encountered. These findings can
