[Cysts of the choroid plexus: personal experience].

Twenty-six cases of fetal choroid plexus cysts were diagnosed using ultrasonography at the Ultrasound Out-patients clinic of the University of Turin during the period 1989-1991. In 21 of these cases fetal karyotype was ascertained since, as has been reported in the literature, cysts of the choroid plexus may be associated with an anomalous karyotype (trisome 18 or 21). One of the 21 cases had an altered karyotype (trisome 21) (4.

[Massive subchorionic fibrin deposit: echographic diagnosis].

Intra-placental sub-chorionic fibrin deposition is a frequent finding but generally does not involve alterations of hemodynamics or the organ's gaseous metabolism. If the deposition is massive, as in the two cases reported here, delayed fetal growth may occur due to altered placental function. Diagnosis using ultrasound is useful both to identify fibrin plaques and to identify possible fetal hypo-development.
