A 24-year-old woman with refractory focal epilepsy was evaluated for epilepsy surgery. MRI showed an extensive malformation of cortical development (MCD) that involved the right perisilvian region and compromised the motor gyrus (figure 1). Functional MRI showed an abnormal location of the motor function with anterior displacement of the pyramidal tract on diffusion tensor imaging tractography (figure 2). Motor mapping using stereoelectroencephalography confirmed these findings. Large MCDs can potentially [...]
