Zenker's Diverticulum

In anatomy, Zenker's diverticulum, also pharyngoesophageal diverticulum, also pharyngeal pouch, is a diverticulum of the mucosa of the pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the esophagus). It is a false diverticulum (not involving all layers of the esophageal wall).

It was named in 1877 by German pathologist Friedrich Albert von Zenker.
