Current concepts of polymicrogyria

Neuroradiology. 2010 Jun;52(6):479-87. doi: 10.1007/s00234-009-0644-2. Epub 2010 Mar 3.


Polymicrogyria is one of the most common malformations of cortical development. It has been known for many years and its clinical and MRI manifestations are well described. Recent advances in imaging, however, have revealed that polymicrogyria has many different appearances on MR imaging, suggesting that is may be a more heterogeneous malformation than previously suspected. The clinical and imaging heterogeneity of polymicrogyria is explored in this review.
