Normal and enlarged lymph nodes:

This is a normal inguinal lymph node. Although a little prominent, it shows  normal vascularity and clear differentiation between the central and peripheral regions- the central region being hyperechoic whilst the periphery shows lower echogenicity.

Enlarged and inflamed lymph node:

  

This lymph node (another patient) shows a markedly enlarged inguinal lymph node (1.2 x 2.7 cms.) with remarkable increase in its vascularity- a classic picture of inguinal lymphadenitis. This patient had a large infected wound in the foot.
