Anatomy of the Pharynx and Cervical Esophagus

The pharynx and upper esophagus are continuous muscular structures allowing multiple functions. The normal imaging appearance can be chal-lenging owing to the complex muscular framework and surrounding fascial layers forming numerous anatomical landmarks. Knowledge of the ex-pected findings and of the anatomical relations of different pharyngeal subsites are crucial to assess lesions and disease extension in this region.
