Fetal choroid plexus cysts in association with cri du chat (5p-) syndrome.

The significance of fetal choroid plexus cysts is controversial. We report a case of antenatally detected cri du chat syndrome (5p-) in one fetus of a twin pregnancy in association with bilateral fetal choroid plexus cysts and unassociated with other structural malformations. Choroid plexus cysts may be nonspecific markers for chromosomal anomalies.

Partial molar pregnancy with fetal survival: an unusual example of confined placental mosaicism.

Background: A pregnancy with a partial molar placenta and a normal fetus is a rare condition. Few guidelines exist for antenatal evaluation and management, particularly with respect to selecting cases for conservative management.

Case: Cytogenetic analysis of chorionic villi showed a triploid placenta, and both amniotic fluid and blood indicated a diploid fetus.

Coronal transcerebellar diameter: an alternate view.

Evaluation of the fetal cerebellum in the axial plane has become an important part of obstetric sonography. We report our experience with an alternate view, the coronal transcerebellar view, in 134 fetuses at gestational ages of 13-30 weeks. There is a linear first-order correlation between axial and coronal transcerebellar diameters.
