We report an association of trigonocephaly and thumb hypoplasia in a 6.5-year-old boy, diagnosed as Baller-Gerold syndrome. In addition to craniosynostosis and radial limb defect, which are constant in this syndrome, our patient presents two unusual features: the first is an epidermal nevus and the second is an agenesis of the middle portion of corpus callosum. This unique type of callosal agenesis in the context of a polymalformative disorder supports the hypothesis that partial agenesis of corpus callosum may be due to an event occurring before the 12th week gestation with continued development of the midline structures.
