A benign, reactive-type lymph node in the left submandibular region
A metastatic lymph node in the right supraclavicular region
Compare the sonographic pattern of the two nodes. In the case of the
metastatic node, the less hypoechogenic tumor replaced almost the
entire node. Note the lack of hilum and the presence of
microcalcification and the disturbed vascularization. The lateral
borders of the metastatic node is blurred.
