case_images: Ultrasonograms of the goiter caused by iodine deficiency in the dog. The echotexture of the left thyroid lobe (A) is homogeneous, whereas the echotexture of the right lobe (B) is heterogenous with some anechoic lesions. Both thyroid lobes are mildly enlarged and well marginated without invasion.

case_images: The echotexture of the right thyroid lobe was heterogeneous, with some anechoic lesions, whereas the echotexture of the left lobe was homogeneous (Figures 1A,B).
case_images: Cytological findings of the goiter caused by iodine deficiency in the dog. Microscopic analysis shows that the cells are polygonal in shape with or without an intercellular border. Nuclei are eccentrically located and have a mild coarse chromatin pattern with basophilic nucleoli. Additionally, there is a low nucleus-to-cytoplasm ratio. Wright-Giemsa.

case_images: Microscopic analysis showed that the cells were polygonal in shape, with or without intercellular borders (Figure 2).
case_images: Ventral (A) and right lateral (B) views of thyroid scintigraphy in the dog with a goiter caused by iodine deficiency. All images were acquired 40 min after the injection of technetium-99m pertechnetate. Markedly increased uptake of technetium-99m pertechnetate is observed in the thyroid mass.
