Chiari I malformation and cloacal exstrophy: report of a patient with both defects of blastogenesis

Abstract

We report on child with Chiari I malformation (CIM) and cloacal exstrophy, a combination of findings that has not been reported previously. CIM and cloacal exstrophy both demonstrate abnormalities that represent maldevelopment of the midline field. This combination of anomalies in this patient suggests an impairment of midline development during blastogenesis.
