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 done pre-operatively for anaplastic thyroid cancer and post-operatively for DTCs. DTC distant metastases sites include the lung (50 %), bone (25 %), lung and bone (20 %), followed by other sites (5 %). The thyroid cancer recurrence rate is reported to range from 7 % to 14 %. Recurrence is usually detected within the first decade after initial disease diagnosis. Large lymph node metastasis is considered the strongest predictor for thyroid cancer recurrence. Post-treatment surveillance for recurrent disease depends on cancer type and staging. Patients with DTC are usually treated with total thyroidectomy and RAI ablation. Patients should have baseline
