The normal imaging appearance of the pharynx and cervical esophagus can be challenging given the numerous interleaved surrounding muscles and numerous connections. This article presents the imaging anatomy of the pharynx and cervical esophagus and also discusses the clinical relevance of selected anatomical structures that have important significance in disease development and extension.
