EP07.48: A very rare association of Turner syndrome with Dandy‐Walker malformation

We present a case of a pregnancy complicated by multiple fetal abnormalities, cystic hygroma, hypoplastic aortic arch, short limbs, bilateral talipes, and Dandy-Walker malformation. The baby became hydropic and subsequently the intrauterine demise was diagnosed at 21+5w gestation. The patient declined prenatal invasive diagnostic tests, however postmortem examination confirmed the ultrasound finding of Dandy-Walker malformation and the karyotype was confirmed as a monosomy X (Turner`s syndrome). A Dandy-Walker malformation is an unusual finding in Turner's syndrome. This is just the second case report that we found in the literature. In conclusion, we should consider a Turner's syndrome as a possible cause for a Dandy-Walker malformation.
