Amniotic Band Syndrome Associated with Exencephaly: A Case Report and Literature Review.

Amniotic band syndrome (ABS) is a rare congenital disease with variable manifestations ranging from simple constriction rings at the extremities to major defects such as exencephaly. Here we report the case of a female baby born full term (39 weeks) from a 35-year-old primiparous mother by cesarean section. In addition to the constriction rings at the extremities (fingers), the newborn presented facial malformations and a cranial anomaly suggestive of exencephaly. Supportive treatment was chosen because of the poor prognosis, and the child died 5 months later. Depending on the anomaly associated with ABS and its complexity, as in our case, genetic studies should be performed whenever possible, and the parents should be informed about the possibility of recurrences and incompatibility with life.
