Pediatric Focal Cortical Dysplasia

  • Etiology: disorder of cortical formation
  • MRI: cortical thickening, blurring of grey matter-white matter junction with abnormal architecture of subcortical layer, T2 hyperintense white matter with or without transmantle sign, T2 hyperintense grey matter, abnormal sulcal or gyral pattern

Radiology Cases of Focal Cortical Dysplasia

MRI of focal cortical dysplasia
Axial T2 (above left), axial FLAIR (above right) and coronal T1 (below) MRI without contrast of the brain show an abnormal gyral pattern of cortical grey matter in the infero-medial aspect of the right frontal lobe that on the axial images is seen to nearly reach the anterior-most aspect of the anterior horn of the right lateral ventricle.
