Figure 1

MRI showing a cortico-subcortical lesion in the lower third of the postcentral gyrus (A-D), with blurring of the grey-white matter junction (coronal FLAIR sequence [A]; post-gadolinium coronal T1WI [B]) and subcortical hyperintensity (A). Sagittal (C) and oblique axial (D) post-gadolinium T1WI reconstructions also exhibit the lesion.

Figure 2

Anatomical relationship between a 3D reconstruction of the patient‘s brain (A), the location of the electrodes in the sagittal plane in relation to the central sulcus (B), and the ictal trace of the SEEG (C).

(A) Pre-resection image of the brain showing the postcentral gyrus, precentral gyrus, central sulcus and sylvian fissure. (B) 3D reconstruction of the patient‘s brain. (C) Post resection image of the brain. PoC: postcentral gyrus; PrC: precentral gyrus; yellow dotted line: central sulcus; green dotted line: Sylvian fissure.

Postoperative MRI showing the cortical resection (white arrow) on coronal plane (inversion recovery and FLAIR sequences) as well as on axial plane (FLAIR sequence).
