Eosinophilic disorders of the gastrointestinal tract are increasingly rare but remain an important cause of long-standing gastrointestinal symptoms. Diagnosis is usually delayed because the disease mimics other inflammatory disorders and is often not suspected initially. We report a series of four cases to highlight the various imaging appearances of this condition. Two patients presented with upper gastrointestinal involvement, one patient presented with small and large bowel involvement, and one patient presented with diffuse involvement of the entire gastrointestinal tract.
