Sclerosing encapsulated peritonitis is a rare entity and it is interpreted as the total or partial encasement of the abdominal organs within a thick fibrocollagenous membrane. The underlying conditions of sclerosing encapsulated peritonitis are multifactorial. Most of the cases are unfortunately diagnosed at laparotomy. It may lead to diagnostic laparotomy because of the acute abdominal signs and symptoms. Adhesiolysis of the sac is enough for the surgical treatment of sclerosing encapsulated peritonitis, unless a non-vital intestinal segment is present which requires resection. Herein, we report a case of sclerosing encapsulated peritonitis with internal herniation findings detected in the preoperative abdominal computed tomography scan and signs of acute abdomen.
