Transient transverse folds of the esophageal mucosa as seen by barium esophagography and on endoscopic examination have been termed "felinization." This finding has been considered a normal variant or has been associated with reflux esophagitis. No symptoms have been associated with its presence. In 280 unselected patients undergoing upper gastrointestinal endoscopy in our clinic, felinization was identified in 24% by prospective visual examination. It was not correlated with sex, age, symptom complex, or common coexistent endoscopic findings. These transverse esophageal folds, although visually interesting, appear to have no clinical significance. The endoscopist should recognize and differentiate them from fixed or persistent folds that can be associated with mucosal disease. (Gastrointest Endosc 1995;42:37-40.).
