Prenatal diagnosis of choroid plexus papillomas of the lateral ventricle. A report of two cases.

Two cases of fetal choroid plexus papillomas diagnosed by ultrasound at 21 weeks of pregnancy are reported. Dilatation of the cerebral lateral ventricle, unilateral in one case, made it possible to see the irregular profile of the choroid plexus that was confirmed, successively, by magnetic resonance imaging and anatomic pathological examination on the aborted fetuses.
