8. Abnormal Neck Lymph Nodes
• Heterogeneous echotexture, calcifications, and cystic areas
• Round Lymph node
• Size is less reliable than shape or architecture
• Lymph nodes measuring > 7mm in short axis are suspicious
Punctate echogenicities in thyroid nodules. (a) Sagittal US image of nodule (arrowheads) containing multiple fine echogenicities (arrow) with no comet-tail artifact. These are highly suggestive of malignancy. FNA and surgery confirmed papillary carcinoma. (b) 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.

Abnormal cervical lymph nodes. (a) Sagittal US image of enlarged node (calipers) with central punctate echogenicities, consistent with microcalcifications, shows mass effect on internal jugular vein (V). Node was proved to be metastatic papillary carcinoma. (b) Sagittal US image of enlarged node (calipers) with cystic component. Node was proved to be metastatic papillary carcinoma.
