We reviewed the literature on the echographic examination of diseased
superficial lymph nodes in the cervical, axillary, internal mammary an
d inguinal regions. The anatomy and the technique of the echographic e
xamination were reviewed followed by the role and limitations of compu
ted tomography and magnetic resonance imaging. The echographic present
ation of normal, inflammatory and tumoral lymph nodes was discussed in
light of the indications for echography of the superficial lymph node
s in ear-nose-throat and breast cancer and in cases of lymphomas.
