Neonatal ileoileocolic intussusception associated with ileal polyp: report of one case.

Neonatal intussusception is an uncommon disease. We report a case of neonatal ileoileocolic intussusception led by an ileal polyp in a female neonate. The patient presented with irritable crying, bilious vomiting and frank bloody stool on the 26th day of life. On physical examination, a mobile abdominal mass was palpated. Abdominal sonography demonstrated a long segment intussusception; associated with a low echogenic mass. At laparotomy, ileoileocolic intussusception led by an ileal polyp was found. Pathology confirmed the diagnosis of polyp. Because intestinal obstruction is the primary manifestation, neonatal intussusception is initially indistinguishable from obstructions due to other reasons like intestinal atresia, congenital bands, necrotizing enterocolitis or midgut volvulus. Our experience showed that although uncommon, intussusception should be considered in the differential diagnosis of intestinal obstruction during the newborn period.
