Dichorionic twin fetuses with VACTERL association.

Although prenatal diagnosis of VACTERL (vertebral defects, anal atresia, cardiac anomaly, tracheal-esophageal fistula with esophageal atresia, renal defects, and radial limb dysplasia) association is not always possible, ultrasonography and magnetic resonance imaging can visualize some of the characteristic findings of this condition. Because infants with this condition usually require significant surgical treatment and care, prenatal detection with those imaging modalities should assist in proper planning for delivery and anticipated care of the neonate. In this report, we present dichorionic twin fetuses, both of whom were found postnatally to have this condition, and suggest the possible relationship between this disorder and intracytoplasmic sperm injection. As far as we know, this is the first report of twin fetuses affected by VACTERL association.
