Prenatal and postnatal evaluation of polymicrogyria with band heterotopia
نویسندگان
چکیده
The coexistence of band heterotopia and polymicrogyria is extremely rare though it has been reported in the presence of corpus callosum anomalies and megalencephaly. We present prenatal and postnatal MRI findings of a rare case of diffuse cortical malformation characterized by polymicrogyria and band heterotopia. Agenesis of the corpus callosum and megalencephaly were also noted. In addition, bilateral closed-lip schizencephaly was identified on postnatal MRI, which has not been previously reported with this combination of imaging findings. Polymicrogyria with band heterotopia can occur and can be diagnosed with fetal MRI. The coexistence of corpus callosum anomalies and megalencephaly comprises a rare phenotype that has been previously described, suggesting an underlying genetic abnormality.

Early prenatal MR imaging diagnosis of polymicrogyria.
The case of a 24-week-old fetus that showed features suggestive of focal cortical developmental anomaly at prenatal MR imaging is presented. The anomaly was confirmed to be polymicrogyria by 34-week prenatal and the 3-day postnatal MR imaging studies. The report demonstrates that the development of polymicrogyria can be assessed throughout different stages by prenatal MR imaging. In the case re...
متن کاملDouble Cortex Syndrome (Subcortical Band Heterotopia): A Case Report
Objective Approximately 5-10% of preschool age children are considered developmentally disabled. Brain Magnetic Resonance Imaging (MRI) plays a key role in the diagnostic evaluation in these children. Many congenital or acquired brain anomalies are revealed with MRIs. Although the majority of these abnormalities are sporadic but patients with subcortical band heterotopia or double cortex syndro...
متن کاملAbnormalities of cortical development and epilepsy
− Malformations of the cerebral cortex (MCC) are often associated with severe epilepsy and developmental delay. About 40% of drug-resistant epilepsies are caused by MCC. Classification of MCC is based on embryological brain development, recognising forms that result from faulty neuronal proliferation, neuronal migration and cortical organisation. Hemimegalencephaly, an enlarged dysplastic hemis...

The malformations of cortical development (MCD) represent a major cause of developmental disabilities, severe epilepsy and reproductive disadvantage. Genes that have been associated to MCD are mainly involved in cell proliferation and specification, neuronal migration and late cortical organization. Lissencephaly-pachygyria-severe band heterotopia are diffuse neuronal migration disorders (NMDs)...
متن کاملEpileptogenic brain malformations: clinical presentation, malformative patterns and indications for genetic testing
We review here those malformations of the cerebral cortex which are most often observed in epilepsy patients, for which a genetic basis has been elucidated or is suspected and give indications for genetic testing. There are three forms of lissencephaly (agyria-pachygyria) resulting from mutations of known genes, which can be distinguished because of their distinctive imaging features. They acco...
