[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.

[Cavitating mesenteric lymph node syndrome]

Cavitating mesenteric lymph node syndrome (CMLNS) is a complication of celiac disease (chronic enteropathy characterized by intolerance to gluten ingestion) that is documented but poorly understood. Patients with CMLNS often present with weight loss that is refractory to treatment, fatigue, and diarrhea associated to clinical signs and laboratory findings of hyposplenism. Computed tomography shows multiple cystic mesenteric masses with a central low attenuation area caused by the presence of fluid and/or adipose material in the central cavity of the mesenteric lymph node.
