Congenital bilateral perisylvian syndrome associated with congenital constriction band syndrome

We report a 7-year-old boy with congenital bilateral perisylvian syndrome and congenital constriction band syndrome. The former is a congenital neurologic syndrome characterized by pseudobulbar palsy, mental retardation, epilepsy, and bilateral perisylvian polymicrogyria. The latter is a malformative disorder with digital ring constrictions and amputations, probably caused by early amnion rupture resulting in entanglement of fetal parts by amniotic strands. We believe that the combination of these two malformative disorders was not coincidental; instead, fetal circulatory disturbance related to chronic abruptio placentae could account for this combination.
