Overview

Zenker's diverticulum (ZD) appears as an out-pouching sac on the MRI scan over the posterior esophagus in the Killian's triangle, a point of weakness in the muscular wall of the hypopharynx surrounded by the cricopharyngeal sphincter and oblique fibers of the inferior constrictor of the pharyngeal muscle. The sac is filled with, fluid, food, contrast materials.
