Image Diagnostic Techniques in EGE

Recent reports have described the endoscopic and radiological findings typical in EGE. Most endoscopic findings tend to be nonspecific, with mucosal hyperemia and thickened gastric folds[14] being the most common. Areas of rough or nodular appearance, erosions, aphthae and ulcers have also been described in EGE. In some cases, the endoscopic findings were described as normal.[13] Findings from capsule endoscopy include multiple erythematous lesions, loss of villi,[15] incomplete strictures with ulcerated mucosa alternating with preserved areas[76] or a mimicking of mucosal diaphragms with complete retention of the capsule.[77] One patient with eosinophilic ascitis showed a bluish discoloration of the deep layers of the intestinal wall without mucosal changes; the authors hypothesized that in this case, eosinophilic infiltration had not affected the mucosa.[78]

Radiological findings in EGE are equally unspecific in two thirds of patient;[14] double contrast radiology findings are usually normal,[14] but may occasionally show thickened folds, irregular or serrated edges in the small intestine walls, nodular contrast defects or slow contrast progression indicative of gastrointestinal hypomotility.
