12-month-old boy presented to our outpatient department with a history of global developmental delay and infantile spasms since age of 6 months diagnosed as a case of pachygyria. (a and b) T2-weighted axial images show hyperintensities in periventricular (single arrow) and bilateral frontoparietal region with frontal predominant cortical thickening (double arrow) with paucity of sulci favoring cortical dysplasia with pachygyria.

MRI of brain showed frontal predominant pachygyria, periventricular, and bilateral frontoparietal symmetric hyperintensities along with "tigroid-like stripes" or "reverse tigroid pattern" (T2-weighted sagittal image showing radial stripes) [Figures 1, 2, 3a and b] and "leopard-like appearance" - scattered dots in form of hyperintensities on a normal background white matter [Figure 3c and d].
12-month-old boy presented to our outpatient department with a history of global developmental delay and infantile spasms since age of 6 months diagnosed as a case of pachygyria. (a and b) T2-weighted axial images show "tigroid-like stripes"(single arrow) along with frontal predominant cortical thickening (double arrow) and (c) fluid-attenuated inversion recovery image shows hyperintensities in bilateral subcortical white matter (thin triple arrow) suggesting myelination abnormality.

MRI of brain showed frontal predominant pachygyria, periventricular, and bilateral frontoparietal symmetric hyperintensities along with "tigroid-like stripes" or "reverse tigroid pattern" (T2-weighted sagittal image showing radial stripes) [Figures 1, 2, 3a and b] and "leopard-like appearance" - scattered dots in form of hyperintensities on a normal background white matter [Figure 3c and d]. Fluid-attenuated inversion recovery image [Figure 2c] showed hyperintensities in bilateral subcortical white matter suggesting myelination abnormality and ruling out the enlargement of perivascular space as a cause of this appearance.
12-month-old boy presented to our outpatient department with a history of global developmental delay and infantile spasms since age of 6 months diagnosed as a case of pachygyria. T2-weighted sagittal images (a and b) show radial stripes (single arrow); (c and d): show scattered dots in form of hyperintensities on a normal background white matter (double arrow) - "leopard-like appearance" along with a normal appearing cerebellum

12-month-old boy presented to our outpatient department with a history of global developmental delay and infantile spasms since age of 6 months diagnosed as a case of pachygyria. Awake electroencephalogram of the child shows background high amplitude polymorphic delta wave activity with multifocal spikes.
