Overview

The ultrasonographic findings of Zenker's diverticulum (ZD) includes iso-echoic or hypo-echoic mass with internal or peripheral echogenic foci and a boundary hypo-echoic zone at the posterior portion of the thyroid gland. High-frequency USG identifies multi-layered appearance, continuous with the esophageal wall. Internal echogenic foci within ZD were often misdiagnosed as punctuate micro-calcifications associated with papillary cancer. Boundary hypo-echoic zone or echogenic line on a sonogram with a connection to the esophagus is associated with ZD. Thyroid USG is done to avoid unnecessary aspiration as it is often misdiagnosed for ZD as a thyroid nodule.
