Which diverticulum protrudes from the anterolateral wall of the cervical esophagus?

• A. Zenker
• B. Esophageal Diverticulum
• C. Killian-Jamieson
• D. Pulsion Diverticulum

Answer: (C)

This item tests knowledge of where different cervical esophageal diverticula arise. Zenker’s diverticulum forms in the posterior wall at the pharyngoesophageal junction, through Killian’s dehiscence, and is located above the cricopharyngeus. In contrast, Killian‑Jamieson diverticulum comes from the anterolateral wall of the cervical esophagus, below the cricopharyngeus, often on the left. That anterolateral cervical esophageal location is what makes Killian‑Jamieson the correct choice. The other options either describe a posterior pharyngoesophageal pouch or are generic terms that don’t specify a cervical anterolateral origin.
