Chronic intussusception associated with ileocecal lymphosarcoma.

A 1011/12-year-old boy with chronic ileocolic intussusception associated with ileocecal lymphosarcoma was decribed. The patient had abdominal pain of 3 months' duration, vomiting, and a firm mass with smooth surface in the right lower abdomen. Barium enema showed intussusception at the distal part of the ascending colon, which was irreducible by hydrostatic pressure. Barium by mouth revealed markedly distended small intestines, which were displaced to the left abdomen. The tumor was inoperable, and the boy died.
