  • Figure 1
    Brain CT
     

    Brain CT shows left hemispheric enlargement/ dysmorphism with falx cerebri shifted to the right. There is irregular contour and decreased sulcation throughout the affected hemisphere. Notice dystrophic calcifications...

     
    Area of Interest: Neuroradiology brain; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Seizure disorders;

    Multiple dystrophic calcifications throughout the left hemisphere, more confluent within the left anterior frontal subcortical white matter, but extending to the supraventricular parietal centrum semiovale.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Seizure disorders;

    Multiple dystrophic calcifications throughout the left hemisphere, more confluent within the left anterior frontal subcortical white matter, but extending to the supraventricular parietal centrum semiovale.

  • Figure 2
    Brain MRI axial T2
     

    MRI brain shows significant dysmorphic enlargement of the left cerebral hemisphere. Diffuse pachygyria/ polymicrogyria results in loss of sulcation, with abnormal left hemispheric myelination.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Seizure disorders;

    Brain MRI coronal T1
     

    MRI T1 coronal brain shows to better extent the volume discrepancy between hemispheres with dysmorphic left hemisphere features with loss of sulcation.

    3D SWAN
     

    3D susceptibility (SWAN) images demonstrate diffuse, irregular magnetic susceptibility artifact throughout the subcortical and deep white matter of the left hemisphere, corresponding to dystrophic calcifications seen...

Brain CT shows left hemispheric enlargement/ dysmorphism with falx cerebri shifted to the right. There is irregular contour and decreased sulcation throughout the affected hemisphere. Notice dystrophic calcifications in supraventricular white matter.
 
Multiple dystrophic calcifications throughout the left hemisphere, more confluent within the left anterior frontal subcortical white matter, but extending to the supraventricular parietal centrum semiovale.
