Cortical thickening is seen in the left frontal lobe with an asymmetric increase in myelination of adjacent subcortical white matter evidenced by T2 hypointensity and T1 hyperintensity. This extends towards the frontal horn of the left lateral ventricle in a radial fashion.
Focal hypointensities on GRE images are seen in bilateral cerebellar hemispheres, possibly microhemorrhages.
Case Discussion
Findings are consistent with focal cortical dysplasia. Focal increase in myelination depicted by reduced T2 and increased T1 signal is often a sign of an underlying focal cortical dysplasia. The patient's EEG showed abnormal discharges from the left frontal lobe and MRI findings are consistent with the same.
