Intussusception in the first month of life is rare; however, it should be c
onsidered a distinct clinical and pathologic entity. Cecal duplication as t
he cause of intussusception in a neonate is extremely rare. We report a cas
e of a newborn with ileocecocolic intussusception. She presented with vomit
ing and bloody stools. Abdominal sonography revealed a target lesion with a
cystic component. We performed a laparotomy and Found an ileocecocolic-typ
e intussusception the which was caused by a cecal duplication cyst. Right h
emicolectomy with ileocolostomy was performed. She remained well at one lea
r follow-up.
