Side view from an esophagram shows an enlarged esophagus filled with contrast material with narrowing close to its connection to the stomach which is a common appearance in a condition called "achalasia." The esophagus of patients with "achalasia" does not relax normally because of an abnormality of the nerves in the wall of the esophagus and therefore it appears narrow.
