Feline esophagus (patient also has hiatal hernia)

Prominence of fine, transverse esophageal folds resulting from contraction of the longitudinal fibers of the muscularis mucosa seen transiently on double contrast barium esophagram examination. The delicate, concentric, transiently appearing folds of feline esophagus should be distinguished from the thicker, interrupted, fixed folds indicative of longitudinal scarring from reflux esophagitis.

  • Can be a normal variant
  • More frequently in patients who have GERD
  • Description has also been used with Eosinophilic esophagitis
