We report an unusual cause of subacute intestinal obstruction in a young adolescent girl, which is a nontubercular abdominal cocoon. Barium meal follow-through revealed "cauliflower"-like appearance of small bowel. The patient underwent an exploratory laparotomy showing thick fibrous-like coverings which were encasing the small bowel loops to form an abdominal cocoon. Fibrocollagenous membrane was excised after adhesiolysis. Histopathological examination of membrane revealed fibrocollagenous membrane with hyaline deposition of nontubercular origin.
