Abdominal cocoon, or sclerosing encapsulating peritonitis, is supposed to be rare cause of intestinal obstruction. It is characterized by totally or partially encasement of small bowel with a thick, fibrotic, cocoon-like membrane. We think this entity is not rare as previously thought. We reported two case-s clinical and imaging findings which diagnosed abdominal cocoon by surgery to increase awareness of this diagnosis. (C) 2013 Elsevier Inc. All rights reserved.
