Kidney bean: Normal cervical nodes are oval or flattened hypoechoic structures with varying amounts of hilar fat. The hilae are usually hypovascular. Malignant infiltration alters the features of the lymph nodes, resulting in enlarged nodes that are usually rounded and show peripheral or mixed vascularity. They may have thickened outer wall, internal echoes, cystic changes, internal nodules, and septations.
