Figure 1 (A-C): (A) Upright LPO view of single-contrast barium swallow demonstrates a shelf-like filling defect along the anterior wall of hypopharynx, at pharyngioesophageal junction s/o web. (B) Jet phenomenon associated with cervical web, usually seen in cases of partial obstruction. (C) Prominent cricopharyngeus muscle may mimic a web. However, it is seen along the posterior wall
