Size disparity of the choroid plexuses of the lateral ventricles: prenatal diagnosis and neonatal outcome.

Fetal choroid plexuses have attracted the attention of perinatologists and geneticists because of the reported association between intrachoroid cysts and chromosomal abnormalities. This report deals with another variation in choroid plexus sonographic appearance-size variation. Sonographic follow-up results as well as neonatal outcome were analysed in five fetuses with these findings. All fetuses had a normal karyotype. Disparate choroid plexuses were not associated with other structural anomalies. None of the fetuses developed ventriculomegaly.
