Fig 2 Imaging demonstrations of CNS malformations in the 1- to 3-year-old group and>3-year-old group A: The irregular contour of the cranium suggests craniosynostosis in a 24-month-old infant (left) and the relatively low density in both cerebral parenchyma was found(right); B: The dysplasia of gyrus in the right hemisphere and the corresponding porencephaly was found on CT image in a 24-month-old infant. The high-density hematoma was also found in the contralateral subdural space; C: The CT indicated the extent low density of both cerebral parenchyma in a 36-month-old infant. D: The absence of left frontal lobe in axial CT was found in a 48-month-old child. The subsequent follow-up demonstrated the barylalia with normal movement function; E: The giant gyrus in the right and the polygyria in left hemisphere on CT was found in a 60-month-old child. F: The dysplasia of left both frontal and parietal lobe was found on MRI in a 48-month-old infant. G: The polygyria was found in both the bilateral frontal and parietal lobe on axial MRI in a 48-month-old infant.
