IS Case 26: Feline Esophagus in the Context of Esophagitis

Single-contrast examination of the esophagus demonstrates feline esophagus and secondary esophageal folds indicative of esophagitis. There is a small hiatal hernia. No gastroesophageal reflux was observed during the study. There is suggestion of a small Schatzki ring.
Similar to the findings described on tantalum esophagrams performed on cats, feline esophagus denotes numerous fine transverse muscosal lines that typically encircle the esophageal lumen. These features can be demonstrated on barium esophagography and endoscopy. Although it is considered a normal variant produced by transient contraction of the muscularis mucosa, it may be associated with esophagitis.
Main differential considerations include chronic reflux esophagitis transverse folds and tertiary contractions. However, the transverse folds of reflux esophagitis tend to be fixed, broad and short. Likewise, tertiary contractions produce single or multiple broad transverse bands that are nonpropulsive in nature. Feline esophagus is of little clinical significance and does not exhibit age or gender predominance.
