EHNS-ESTRO H&N course
Florence, June 2016
Recommendations for the node-positive
neck
•
In case of involvement of level II, delineation of the
retrostyloid space
(level VIIb)
•
In case of involvement of level IV and/or Vb, delineation of
the
subclavicular fossae
(level IVb and/or Vc)
•
When a node is located at the boundary between two levels
(e.g. level Ib and II), delineation of the two levels
•
When node(s) abut a muscle (e.g. SCM or para-spinal),
delineation of the muscle by 10-20 mm in all directions
