We report on a stillborn boy with frontonasal malformation (Sedano-Jiràsek type D-DeMyer type I), associated with encephalocoele, occipital meningocele and preaxial polydactyly of the feet. This form of frontonasal dysplasia was documented previously in a few other cases with various combinations of postaxial polydactyly, tibial hypoplasia, epibulbar dermoid, occipital encephalocoele, corpus callosum agenesis and Dandy-Walker malformation. Most cases are sporadic.
