Comment on: "Anatomical distribution and prognostic heterogeneity in glioma: unique clinical features of occipital glioblastoma".

Abstract

Strategy for occipital isolation by disconnecting convergent white matter fibers. A region of interest (ROI, yellow sphere) was placed in the occipital lobe, and tractography shows streamlines from the ROI. Two major bundles course along the bottom of the parietooccipital fissure (POF) and the trigone of the lateral ventricle. The anterior resection border (light-blue line) is defined by a line connecting the bottom of the POF to the trigone; the lateral resection border (green line) corresponds to the trigonal width measured from the midline. blue line and triangle, trigone of the lateral ventricle; red line and arrow, POF; yellow circle, convergence of fibers along the ventricular wall.
