Zenker's diverticulum is a type of diverticulum that develops in the hypopharynx, typically between the cricopharyngeus (CP) muscle and the inferior pharyngeal constrictor muscle. It only involves the mucosa and submucosal layers and does not involve the muscular layer, hence making it a false diverticulum. It may also occur in other parts of the esophagus, such as between the oblique and transverse fibers of the CP muscle, known as Killian-Jamieson area, and between the CP muscle and the esophageal muscles, known as Laimer triangle.[1][2][3]
