title: Cystic hygromata in trisomy 18 and 21.
abstract: Prenatal diagnosis of cystic hygromata by means of ultrasound examination is possible and highly accurate. Although this is usually associated with Turner's syndrome especially if there is co-existent hydrops fetalis we report three cases in which cystic hygromata were associated with trisomies; two cases of trisomy 21 and one of trisomy 18.
