Abstract
Prenatal ultrasound diagnosis of ileal duplication was made in a fetus of 28 weeks gestation. The child was born at 37 weeks gestation by cesarean section. After birth, right abdominal mass was palpable and intestinal obstruction was increased. Resection of the ileal duplication was performed on the 12th day of life. Early recognition by ultrasound allowed for adequate planning and preparation of management between obstericians, neonatologists and pediatric surgeons.
