The double contrast esophagram image in question is indicative of a condition related to the esophagus. The provided options suggest various esophageal conditions. The features seen on the radiograph align with the appearance of a "Feline oesophagus," which is characterized by transverse, ring-like indentations resembling a cat's esophagus. This appearance typically results from transient esophageal contractions or muscular spasms. Comparing the options:
- Esophageal atresia: A congenital condition where part of the esophagus is absent, but doesn't normally exhibit the ring-like pattern seen in the image.
- Esophageal stenosis: Refers to a narrowing, but doesn't present the cat-like appearance as described.
- Tracheoesophageal fistula: A connection between the trachea and esophagus, typically diagnosed by contrast entering the trachea during swallowing studies, rather than esophagram patterns.
Therefore, based on the radiograph description, Feline oesophagus is the condition represented in the image.
