FIG 1. Images from the intact cadaver of a patient with known GBM.
A, Axial 8-T GE MR image (matrix = 1024 x 1024;TR/TE = 600/12; flip angle = 20°) in the patient with GBM at the level of the trigone of the lateral ventricles (T) and the level of the splenium (S) demonstrates an exophytic mass extending into the left lateral ventricle. A = anterior, P = posterior.
B–D, Reticulin-stained sections (original magnification x100) correspond to an area of normal gray matter (B), the focus depicted by the arrow in A (C), and the focus depicted by the arrowhead in A (D). The arrow in B depicts the sulcus. Image in C shows an area of high vascular density and large vessels. Image in D corresponds to an area of vascularity and vessel size similar to that of the gray matter in the tumor bed. Vessels are depicted by arrows in C and D.
