case_images: Axial CT view of the brain. Hypertrophy of left temporal, occipital, and parietal lobes with displacement of posterior falx to the opposite side is observed with dystrophic calcification within hypodense left parieto-occipital white matter. Left frontal lobe appears relatively normal

case_images: Occipital horn of left lateral ventricle appeared effaced [Figure 1].
case_images: (A) T1-weighted axial MRI reveals increased white matter volume in left temporo-parieto-occipital cerebral region causing enlargement of these lobes, with associated heterotopias and polymicrogyria. (B) T2-weighted axial MRI depicts hyperintense signal in the periventricular white matter of affected lobes, with normal left frontal lobe

case_images: T1-weighted images revealed increased white matter volume in left temporo-parieto-occipital cerebral region causing enlargement of these lobes, with associated heterotopias and polymicrogyria [Figure 2A]. T2-weighted images depicted hyperintense signal in the periventricular white matter of affected lobes [Figure 2A].
case_images: (A) T1 inversion recovery axial image demonstrates periventricular white matter signal intensity changes (red arrow). (B) T1 inversion recovery axial image shows polymicrogyria pattern (white arrow) and heterotopia (black arrow) excellently. Corpus callosum appears normal

case_images: T1 inversion recovery axial images demonstrated polymicrogyria pattern and heterotopias distinctly [Figure 3A and B].
case_images: FLAIR coronal sequence. Left hippocampus appears normal in size but shows mildly increased signal intensity

case_images: T1-inversion recovery and fluid-attenuated inversion recovery (FLAIR) coronal sequences, the left hippocampus appeared normal in size, though the signal intensity was mildly increased [Figure 4]. T2* gradient echo sequences revealed an area of blooming in left occipital white matter, which corresponded to the areas of calcification noted on the NCCT scan.
