Objective To investigate the imaging characters of abdominal cocoon.Methods Six cases of abdominal cocoon proved by surgery and pathologic findings were retrospectively analyzed. Abdominal plain X-ray and CT were performed in 6 cases.The gastrointestinal barium meal series were undergone in 4 cases.The imaging findings were analyzed.Results Abdominal plain X-ray suggested intestinal obstruction in 3 of 6 cases.The gastrointestinal barium meal showed"cauliflower sign"or "concertina pattern"in all of the 4 cases;CT images revealed a conglomeration of multiple small bowel loops in all 6 cases and the intestinal loops seemed to be encapsulated in a membranelike sac.Conclusion The imaging features of gastrointestinal barium meal and CT scan could suggest the diagnose of abdominal cocoon.
