100 consecutive cases of papillary cancer - case 003 (ultrasonographic picture 1b)

Right lobe, transverse scan. The lesion has partly blurred (red arrows) and partly spiculated (yellow arrows) margins. The extent of ill-defined parts of the border exceeds 50%. Although this presentation corresponds to thyroiditis, the fact that there are one or two relatively large lesions in the lobe should raise the possibility of nodular origin, namely papillary carcinoma. Green arrows point to that part of the nodule which echogenicity is identical to the extrathyroidal strap muscle. It means that although we have no proof of extrathyroidal spread, this possibility cannot be excluded.
