Abstract

Polymicrogyria
is a developmental anomaly which has been diagnosed in recent years due to
improvements in neuroimaging methods. It may present with very different
clinical findings. It can be seen in many different patterns. It can be found
with different nervous system anomalies. In this article, different
polymicrogyria patterns and associated anomalies detected in childhood are
presented with MRI findings.
