title: Massive enlargement of the ileocecal valve due to lymphoid hyperplasia.
abstract: Two children with unusual infiltration of the ileocecal valve by lymphoid tissue are described. The large filling defect identified on barium enema may suggest a number of conditions. Operative resection will exclude the possibility of a malignant process and will reduce the chance of recurrent intussusception.
