Normal act of swallowing motion. There is a moderate size Zenker's diverticulum at the C5 spinal level. The diverticular neck is approximately 6 mm and neck to base diameter is approximately 17 mm. Contrast remains within the Zenker's diverticulum. Just below the level of the diverticulum neck, there is smooth narrowing of the lumen of the oesophagus, likely a combination of extrinsic compression and muscular spasm of the cricopharyngeus. No further obstruction and contrast advances into stomach.
