✦ Synopsis

We present the first report of prenatally diagnosed Dandy-Walker malformation with the karyotype of partial trisomy 11 and 22 due to familial translocation t(l1;22)(q23;qll) inherited in three generations. We demonstrate that the Dandy-Walker malformation can be an associated congenital malformation of supernumerary der( )t( 11;22) syndrome and emphasize the importance of chromosomal analysis and genetic counselling in the obstetric management of prenatally diagnosed Dandy-Walker malformation.
