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.
