Abstract
A 30-year-old woman was found to be carrying monochorionic-diamniotic twins at 7 weeks of gestation. The growth-retarded fetus died at 21 weeks of gestation. At 28 weeks of gestation, periventricular leukomalacia was detected in the brain of the surviving fetus by transvaginal ultrasonography. A female baby presenting with microcephaly was born at 39 weeks of gestation, and CT of the brain showed microcephaly and marked hydrocephalus. At 12 months of age, the surviving infant presented with severe physical growth retardation, and frequent episodes of clonic convulsions.
