Ultrasonographic diagnosis of fetal cystic hygroma
1Department of Obstetrics & Gynecology, Chang Gung Memorial Hospital, Taiwan, R.O.C.
Prenatal diagnosis of seven cases of fetal cystic hygroma was characterized by multiloculated cystic mass with septated appearance in relation to the fetal head and neck, as well as various degree of lymphedema and peritoneal effusion and no direct communication with the central nervous system. Karyotype studies were performed in four cases and a composite of karyotypes from literatures is presented. The sonographic appearances and cytogenetic analyses will provide the significant framework needed for accurate prenatal diagnosis and genetic counseling.
