Abstract

The omphalocele–exstrophy–imperforate anus–spinal defect (OEIS) complex is a combination of congenital birth defects. This disease is rare and difficult to diagnose during pregnancy. However, if omphalocele, lumbosacral meningomyelocele, and difficulty in visualizing the bladder are observed on prenatal ultrasonography, the OEIS complex should be suspected. Prenatal diagnosis is important because this disease requires sophisticated multidisciplinary management to avoid excessive mor bidity. We report a prenatally suspected case of OEIS complex in a fetus of monozygotic twins con ceived by in vitro fertilization, which was later diagnosed after birth with omphalocele, bladder exstrophy, vesicointestinal fistula, imperforate anus, meningomyelocele, and club feet.
