PEREZ O, Gonzalo; ZEREGA R, Mario  y  CORTES A, Claudio. Radiological signs: Feline esophagus. Rev. chil. radiol. [online]. 2012, vol.18, n.1, pp. 36-38. ISSN 0717-9308.  doi: 10.4067/S0717-93082012000100008.

Feline esophagus is the benign transient fine circumferential transverse folds that arise during double-contrast esophagography. Accurate discrimination of this entity is relevant due to its association with gastroesophageal reflux and hiatal hernia. Among the differential diagnoses, fixed folds secondary to reflux esophagitis and eosinophilic esophagitis have to be considered.
