Ultrasonography of superficial lymph nodes: benign vs. malignant

Abstract

The aim of the paper is to review and illustrate the current status of the knowledge on the applications of ultrasonography in superficial lymph node disease diagnosis. The grey-scale and Doppler ultrasonographic signs pointing to benignity or malignancy are presented, illustrated and their diagnostic usefulness is discussed. Peculiar types of lymphadenopathy such as inflammatory, tuberculous, lymphoma and metastasis of different origins are also discussed. The paper briefly reviews the nodal applications of some recent technical developments such as contrast and sonoelastography.
