Radiographic abnormalities in eosinophilic esophagitis.
Eosinophilic gastroenteritis is an unusual condition of unknown cause in which there is eosinophilic infiltration of the gastrointestinal tract usually accompanied by a peripheral eosinophilia. Rarely, it can also involve the esophagus. Recently, the authors have encountered 3 cases of eosinophilic infiltration of the esophagus. All patients had a strong history of allergies. Two of our patients have had upper esophageal strictures, as have 2 other previously reported cases. This appears to be the most common manifestation. One patient had polypoid lesions of the esophagus as well as of the rest of the gastrointestinal tract. Motility disturbances may also be present. Although steroid treatment may be beneficial, the esophageal strictures usually require mechanical dilatation to relieve submucosal fibrosis. This entity should be considered in any patient who has an esophageal disorder in the presence of either a strong history of allergy or peripheral eosinophilia.
