Abstract Peritoneal encapsulation (PE) is a rare condition that has been described interchangeably with sclerosing encapsulated peritonitis as well as abdominal cocoon. We report an otherwise well 38-year-old man who presented with two episodes of intestinal obstruction about two months apart. Computed tomography (CT) of the abdomen showed characteristic features of the PE syndrome. Exploratory laparotomy was performed and small bowel was freed of adhesions and the encapsulation. Post-operative recovery was uneventful. PE is an extremely rare congenital condition in which there is abnormal return of the midgut loop to the abdominal cavity in the early stages of development. The small intestine is thus covered by the original dorsal mesentery, forming the characteristic accessory peritoneal sac. Management of cases is difficult as CT findings may not be characteristic and may only be diagnosed at laparotomy.
