Abstract

Hyperextended neck of the fetal head is among the various fetal attitudes detected by prenatal sonography. Various etiologies may lead to hyperextension of the fetal head, including fetal anomalies such as structural abnormalities, conjoined twins and fetal neck masses, nuchal cord and uterine factors such as leiomyoma and uterine malformations. The importance of the precise prenatal diagnosis of this condition relates not only to the delivery mode, but also to the detection of associated conditions, as noted above. We report a case of a fetus whose persistent hyperextended neck was detected by midtrimester sonography, and who later demonstrated ventriculomegaly and lung immaturity in the 3rd trimester.
