USE OF 3-DIMENSIONAL ULTRASOUND TO ESTABLISH THE PRENATAL-DIAGNOSIS OF FRYNS SYNDROME

Three-dimensional (3D) imaging permits surface reconstructions that al low a better view of the appearance of organs. We report a case of a f etus with cystic hygroma diagnosed at 11 weeks of gestation, associate d with a diaphragmatic hernia. With the 3D reconstruction, we examined the fetal face much more easily, which presented facial dysmorphology , retrognathia, macrostomia and a broad nasal bridge. The conjunctions of these pathological features and a normal karyotype allowed to esta blish a prenatal diagnosis of Fryns syndrome, confirmed by autopsy.
