[Primary eosinophilic enteritis: a case report].

Primary eosinophilic enteritis is a rare entity that is characterized by eosinophil infiltration in the different layers of the small bowel. The symptoms depend on the site of infiltration and the layers affected. High blood levels of eosinophils are usually present. Computed tomography plays a fundamental role in the evaluation of this disease. We present a case of primary eosinophilic enteritis diagnosed on the basis of clinical, laboratory, and CT findings.
