NCIt related terms : CERVICAL LYMPH NODE LEVEL V;
NCIt definition : Neck lymph node boundary level V contains the posterior triangle lymph node group.
It includes the lymph nodes located along the lower half of the spinal accessory nerve
and the transverse cervical artery. The supraclavicular nodes are also included in
this group. It is divided into sublevels VA and VB. The following anatomical structures
define sublevel VA: Superior: apex of the convergence of the sternocleidomastoid and
trapezius muscles; inferior: horizontal plane defined by the lower border of the cricoid
cartilage; anterior (medial): posterior border of the sternocleidomastoid muscle or
sensory branches of the cervical plexus; posterior (lateral): anterior border of the
trapezius muscle. The following anatomical structures define sublevel VB: Superior:
horizontal plane defined by the lower border of the cricoid cartilage; inferior: clavicle;
anterior (medial): posterior border of the sternocleidomastoid muscle; posterior (lateral):
anterior border of the trapezius muscle. (partially adapted from AJCC 8th ed.);
Alternative definition : CDISC: Cervical lymph nodes located in the posterior triangle group located posteriorly
to the sternocleidomastoid muscle around the lower part of the spinal accessory nerve
and the transverse cervical vessels.;
