case_images: (a) Preoperative T1-weighted magnetic resonance imaging (MRI) image (coronal view) showing periventricular old ischemia alongside cerebospinal fuild (CSF)-filled cleft in the right-sided hemisphere. (b) Preoperative T2-weighted MRI image (axial view) revealing periventricular longstanding ischemic changes and unilateral CSF-filled cleft in the right hemisphere extending from the frontal horn of the lateral ventricle to the Sylvian fissure.
