(1) The purpose of this educational exhibit is describe the imaging patterns of elastography in solid or cystic/solid benign and malign cervical lymph nodes; (2) To establish a mean index in the solid component of benign or malign cervical lymph nodes; (3) To compare elastography results with FNA or surgery findings; (4) To be able to reproduce the static elatography step by step after reading this apresentation.

Cervical lymph nodes are frequent and its cause usually is confirmed by FNA or surgery. Static elatography is a new ultrasound modality that provides information about tissue distortion under local pressure. Basically there are three sorts of elastography: static, share wave and ARFI. We used the static elastography. Hard nodes are supposed to be malign whereas benign ones are usually soft. We made a retrospective study with 64 cases and our results are similar to the worldwide experience. However there is no consensus regarding the elastography index concerning benignity or malignity nature. In our study benign nodules have an index mean of 1,6 whereas a mean index of 6,0 or more is certainly considered to be malign.
