Zenker´s Diverticula

The radiologic study shows the pharyngoesophageal (Zenker’s) diverticulum.

Esophageal diverticula are more or less pronounced
saccular protrusions of the esophageal wall. Traction
diverticula (e.g., caused by extrinsic traction) affect the
entire wall thickness, while in pulsion diverticula only the
mucosa and submucosa protrude through a gap in the
muscular wall. There are three sites of predilection for
diverticula in the esophagus: cervical diverticula
(synonym: Zenker diverticula, comprising approximately
70% of all esophageal diverticula), thoracic diverticula
(approximately 22%), and epiphrenic diverticula
(approximately 8%)
