Liquid contrast traverses the oesophagus quickly, however, there is an area of persistent narrowing at around the level of the thoracic inlet extending for approximately 7 cm. This has smooth shoulders and no definite ulceration. However, numerous pseudodiverticula are noted here and throughout the more distal oesophagus. No further strictures are identified and the gastro-oesophageal junction appears unremarkable.
There was considerable hold-up to contrast-stained marshmallow at the area of focal oesophageal narrowing (arrow). This likely accounts for the patient's symptomatology.
