    The family had a 5-year-old daughter with a Dandy-Walker malformation and 9p trisomy. This pregnancy was terminated after sonographic examination showed bilateral ventriculomegaly, brachycephaly and a Dandy-Walker malformation with an enalrged cisterna magna and absence of the cerebellar vermis.
