Barium swallows reveal a segmental stricture with irregularity in the posterior aspect of the upper oesophagus, measuring about 4 cm in length, suggesting tumoral infiltration. The contrast media stasis is evident proximal to the stricture that causes some contrast aspiration into the trachea.
In addition, mild transient border irregularity is observed in the distal two-thirds of the oesophagus, suggesting motility disorder.
Small-sized sliding hiatal hernia is also evident.
