A member asked:

What can ultrasound of neck lymph nodes show?

A doctor has provided 1 answer

Normal lymph nodes: Have a kidney bean appearance with fat in the central part of the node. This configuration usually persists when nodes are enlarged by a benign inflammatory response. Nodes involved with cancer cells often loose the central fat, enlarge asymmetrically, have an irregular outer surface, and show increased blood flow in the outer surface of the node.
