Intestinal obstruction due to Ascaris lumbricoides mimicking intussusception.

Two children were admitted for clinical and radiologic signs of small-bowel obstruction. Examination revealed an abdominal mass that was suspected of being a mass of intussusception. Bowel obstruction caused by Ascaris lumbricoides was found at surgery. The laboratory, radiologic, and surgical findings are presented with a short review of the literature with emphasis on diagnosis, incidence, complications, and treatment.
