Intracranial cystic lesions and polydactyly associated with acrocallosal syndrome: Sonographic findings in two cases.

We describe two cases of intracranial cystic lesions associated with acrocallosal syndrome. These fetal anomalies were detected on antenatal sonography and confirmed postnatally. Imaging findings include corpus callosum agenesis with interhemispheric cysts and craniofacial anomalies associated with polydactyly.
