The oesophagus is massively dilated and filled with food debris. It is compressing the upper trachea and displacing the carina and left atrium anteriorly. There is no obstructing oesophageal mass or wall thickening. The stomach is collapsed. No evidence of aspiration or consolidation in the lungs.
CT of the chest confirms upper airway compression from a dilated oesophagus. The distal narrowing suggests achalasia.
