A, Axial T2-weighted image reveals thickening of the cortical gray matter at the medial aspect of both frontal lobes, compatible with bifrontal cortical dysplasia (short arrows). Also seen is a strip of ectopic gray matter extending from the head of the right caudate nuclei to the orbitofrontal cortex (long arrow).B, Coronal FLAIR image shows a strip of ectopic gray matter extending from the head of the right caudate nuclei to the orbitofrontal cortex (long arrow) as well as bifrontal thickening of the cortical gray matter (short arrows).
