27. They are found in 4%–8% of adults by means of palpation, in 10%–41% by Transverse US image of nodule (arrowheads) containing cystic areas with punctate echogenicities and comet-tail artifact (arrow) consistent with colloid crystals in a benign nodule. Artefacto en cola de cometa

31. solid nodule (Fig 2a) are associated with Transverse US images of mostly cystic thyroid nodule with a mural component containing flow. (a) Gray-scale image shows predominantly cystic nodule (calipers) with small solid-appearing mural component (arrowheads). (b) Addition of color Doppler mode demon-strates flow within mural component (arrowheads), confirming that it is tissue and not debris. US-guided FNA can be directed into this area. The lesion was benign at cytologic examination.

37. Longitudinal thyroid ultrasound showing a papillary microcarcinoma with punctate calcification(arrow) in a 24-year-old woman.

39. Nodules and Cancer Thyroid nodules are very common: Figure 1. Punctate echogenicities in thyroid nodules. (a) Sagittal US image of nodule (arrow-heads) containing multiple fine echogenicities (arrow) with no comet-tail artifact. These are highly suggestive of malignancy. FNA and surgery confirmed papillary carcinoma.

41. Adenopatía metastásica Sagittal US image of enlarged node (cali-pers) with central punctate echogenicities, consistent with microcalcifications, shows mass effect on internal jugular vein (V). Node was proved to be metastatic papillary carci-noma.

43. Figure 9. Follicular adenoma in a 30-year-old woman. Transverse sonogram of the left lobe of the thyroid shows a follicular adenoma with a hypoechoic halo (arrows).

45. Hu¨ rthle cell (follicular) carcinoma in a 60-year-old woman. (a) Transverse sonogram of the left lobe of the thyroid shows a partially cystic tumor with solid internal projections (arrows) and thick walls.

47. Medullary thyroid carcinoma in a 32-year-old man. (a) Transverse sonogram of the right lobe of the thyroid shows a large nodule with coarse calcification and posterior acoustic shadowing (arrows). (b) Axial computed tomographic (CT) image shows the nodule with an internal focus of coarse calcification (arrows).
