Post Cricoid Carcinoma-CT

This is a 45 year old female with post cricoid carcinoma. The postcricoid region, pyriform sinus, and posterior hypopharyngeal wall comprise the hypopharynx. Tumors rarely appear in the posterior pharyngeal wall or postcricoid region without also involving the pyriform sinus. Well known etiological association is with Plummer-Vinson syndrome (Paterson-Brown-Kelly syndrome). The syndrome includes hypopharyngeal webs, usually centered in the postcricoid area.
