The anatomy of the neck is complex, with many critical structures crowded together in a relatively small cross sectional area. Many structures in the neck also have similar soft tissue density or signal which further complicates interpretation for the radiologist, who relies on tissue differences to create contrast resolution and distinguish structures. Head and neck cancer incidence worldwide exceeds 550,000 cases per year with diagnosis, treatment, and prognosis relying highly on a thorough knowledge of this compact space. This chapter will focus on reviewing head and neck anatomy with special attention to nodal anatomy and discussing the expected patterns of nodal spread in head and neck cancers.
