title: Colonoscopic diagnosis of lymphoid hyperplasia causing recurrent intussusception: report of a case.
abstract: This paper describes a 6-year-old boy with recurrent ileocecal intussusception due to lymphoid hyperplasia in the terminal ileum, which was diagnosed preoperatively by colonoscopy. At the age of 3 years, he developed diarrhea and a tender abdominal mass. He was diagnosed as having intussusception by ultrasound and was treated by hydrostatic barium enema. After resolution, he had three recurrent episodes of intussusception. A contrast barium enema revealed a small mass in the ileocecal region. Colonoscopy showed several exaggerated folds of the terminal ileum and a biopsy showed lymphoid hyperplasia. Because the repeated intussusception seemed to have been caused by the lymphoid hyperplasia in the terminal ileum, he underwent an ileocecal resection without any subsequent recurrence. Based on the above findings, we conclude that a colonoscopy may thus be useful both for diagnosing lymphoid hyperplasia in the terminal ileum as a cause of recurrent intussusception and for deciding how to manage it.
