Isolated congenital arhinia: Fetal magnetic resonance imaging and pediatric computed tomography 3D reconstructions, long-term follow-up and review of the literature.

The complete absence of the nose, arhinia, is a malformation most often associated with severe brain malformations. However, arhinia can be isolated, but only a few cases have been described. The prenatal diagnosis of isolated arhinia is also rarely described, with only three cases describing their follow-up, mostly in the first months of life. In this case report, we describe the prenatal diagnosis of isolated arhinia and the long-term follow-up of 8 years with normal psychological and cognitive development. We also demonstrated the fetal magnetic resonance imaging and pediatric computed tomography three-dimensional reconstructions of the face.
