Crouzon syndrome associated with acanthosis nigricans: Prenatal 2D and 3D ultrasound findings and postnatal 3D CT findings

Abstract

Crouzon syndrome with acanthosis nigricans (CAN) is a very rare condition with an approximate prevalence of 1 per 1 million newborns. We add the first report on prenatal 2D and 3D ultrasound findings in CAN. In addition we present the postnatal 3D CT findings. The diagnosis was confirmed by molecular testing.
