(a) The transverse thyroid sonogram shows a diffusely enlarged thyroid gland with isoechoic and non-coarsened background parenchyma. (b) A 0.4 x 0.3cm sized hypoechoic nodule (arrow) in the left thyroid.

The thyroid US demonstrated a diffusely enlarged thyroid gland with a 0.4x0.3cm sized hypoechoic nodule in the left thyroid (Figure 1).
Pathological finding reveals a papillary carcinoma. (a) x400, hematoxylin and eosin stain and lymphocytic patches predominantly in peripheral portions of the thyroid parenchyma (b) x100, hematoxylin and eosin stain.

There were rarely lymphoid follicles with germinal center (Figure 2).
(a) Preoperative Tc-99m scintigraphy checked at a local medical clinic shows normal uptake of the tracer. (b) Postoperative Tc-99m scintigraphy shows faint visualization of the right thyroid lobe.

Tg level was normalized (Table 1). Tc-99m scintigraphy showed faint visualization of the right thyroid lobes, and 24-hour radioactive uptake of 131I was 0.7% (Figure 3b), which suggested destructive thyroiditis.
