This 86 year old female presented with a 2 year history of food sticking in throat, followed by regurgitation of undigested food particles. This lateral view from a barium swallow demostrates a Zenker’s diverticulum.
A Zenker’s diverticulum originates in the posterior wall of the hypopharynx at an anatomical weak point between cricopharyngeus and inferior constrictor, known as Killian’s dehiscence. Food may collect in the diverticulum, leading to regurgitation, aspiration or oesophageal obstruction.
