Sonography of Zenker Diverticulum

Zenker diverticulum, also known as a pharyngeal pouch, is the most common type of esophageal diverticulum. While sonography is not the imaging modality of choice for diagnosis of a suspected diverticulum, it is not uncommon to detect during a sonographic examination. Typically, a Zenker diverticulum is located in close proximity to the left thyroid gland.
