 Radiologically, the term "ringed esophagus" has been used for the appearance of eosinophilic esophagitis on barium swallow studies to contrast with the appearance of transient transverse folds sometimes seen with esophageal reflux (termed "feline esophagus").Treatment strategies may include medication, dietary modification to exclude food allergens, and mechanical dilatation of the esophagus.Dietary treatment can be effective, as there does appear to be a role of allergy in the development of EOE.
