RESUMEN
The amniotic band syndrome is rare congenital deformity, presumably due to rupture of amniotic sac during the early pregnancy and appears to cause fetal injury through deformation, malformation, or disruption. This syndrome is given many names yet follows a clearly defined clinical pattern. The diagnosis was based on sonographic visualization of either amniotic bands or bands associated with fetal deformation or deformities in nonembryologic distribution. Recently, we experienced a case of amniotic band syndrome, in which partial absence of cranial bone, asymmetric facial dysmorphism and amputation of right lower leg were detected. At our best knowledge, this is one of few case describing prenatal ultrasound diagnosis of amniotic band syndrome in Korea. So, we present this case with a brief review of the literatures.
