title: Eosinophilic enteritis: CT features.
abstract: We report CT features of four cases of Eosinophilic enteritis. The disease involves the jejunum in one case, the ileum in two cases, and the colon in the remaining case. Two cases demonstrate a predominantly mucosal type of eosinophilic enteritis, while the other two cases demonstrate a predominantly subserosal type. CT findings include bowel wall thickening in four cases, bowel fold thickening in two cases, layering of the bowel wall in two cases, luminal narrowing without obstruction in three cases, an intra-luminal granuloma mimicking a huge polyp in one case, an extra-luminal irregular granuloma markedly enhancing and slightly necrosing in one case, mesenteric lymphadenopathy with peripheral rim-like enhancement and marked necrosis in one case and ascites in one case. CT findings are more characteristic of an inflammatory disease rather than of a tumor, and these findings are helpful for assessing the extent and location of the disease. Moreover, combined with its typical clinical manifestations, CT findings may lead to the correct diagnosis.
