Amniotic Band Syndrome

  • Etiology: rupture of amnion early in pregnancy leads to formation of proteinaceous bands which protrude into amniotic cavity and entrap fetal parts and disrupt tissue growth
  • Imaging: asymmetric pattern, single or multiple defects – craniofacial abnormalities / limb constrictions or amputations / syndactyly
