Eosinophilic gastritis. Radiologic-pathologic correlation (RPC) from the Armed Forces Institute of Pathology (AFIP)

Eosinophilic gastroenteritis may involve the gastrointestinal tract locally ofr diffusely. When localized to the stomach, the preferred terminology is "eosinophilic gastritis". Pathologically, this entity is characterized by a high eosinophil count (which closely follows the symptomatology) and diffuse infiltration of the antral wall by eosinophils. Typical roentgenographic manifestations include gastric antral rigidity, thickened folds, and mucosal nodules. The differential diagnosis is discussed. Correct diagnosis is vital because of the benign nature of the disease and good response to conservative therapy.
