The spinal accessory nerve is often in the field of view of neck ultrasound imaging, however, can be overlooked and underappreciated during sonographic neck imaging and ultrasound-guided lymph node biopsies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method:<\/jats:title>\n                    <jats:p>A scoping review of the literature was conducted to assess current knowledge regarding sonographic imaging of the spinal accessory nerve.
