Summary. Five cases of abnormality in twin pregnancies, detected by ultrasound examination during the second trimester, are reported. In four pregnancies there was a fetal malformation: discordant anencephaly, a monozygotic, heterokaryotypic twin pregnancy with coexistant Turner's syndrome and intrauterine death, concordant body stalk syndrome, and a dicephalus monster. In the other pregnancy one fetus dies in utero to become a fetus papyraceous. Four of the pregnancies were associated with raised levels of maternal serum α‐fetoprotein, by singleton standards. Ultrasound examination proved of value in each case. Three pregnancies were terminated.
