title: The "string-sign" in sonographic diagnosis of diamniotic twin pregnancy.
abstract: A consistent echogenic line, the "String-sign" resulting from opposed amniotic membranes in diamniotic twin pregnancy as seen at sonography is reported. The string sign is especially useful in the detection of unsuspected twinning in late pregnancy and it should be taken as a definite pointer to multiple pregnancy whenever its presence is established at any stage in pregnancy.
