Abdominal cocoon syndrome is defined as idiopathic encapsulation of the bowel within a fibrocollagenous membrane and is considered as a rare cause of small bowel obstruction. A 15-year-old female presented complaining of right lower abdominal pain, distension and vomiting for 24 hours with previous similar attacks in the last four years. She had no another significant medical or surgical history. Computed tomography study revealed matted mildly distended bowel loops centrally with a suspicion of acute appendicitis. Next day, abdominal pain was the only clinical finding and acute appendicitis was the primary diagnosis. During surgery, most of the small bowel was found to be encapsulated within a cocoon-like fibrous membrane. The appendix was congested. Appendectomy, full resection of the membrane and dense adhesiolysis were performed. Herein, we will present the first reported case from Somalia and discuss the radiological findings affecting the management for such a rare disease.
