Consecutive patients with the final diagnosis of Hashimoto's thyroiditis - case 5 (1782) (ultrasonographic picture 1)

Right lobe, transverse view. There is an iso/hyperechoic nodule presenting halo sign. If we judge the echogenicity of a nodule in absolute sense, i.e. comparing it to a healthy thyroid then the nodule should be considered minimally/moderately hypoechoic.
