FIG 3. Lateral arteriogram obtained with a left carotid injection demonstrates tortuous vascularity (arrows and arrowheads) in the tumor bed within the glioblastoma multiforme. These findings were also identified on the 8-T images (Figs 1 and 2). However, the normal transmedullary veins and the smaller vessels are less conspicuous on DSA images than on 8-T images. A indicates anterior; DLV, direct lateral vein; I, inferior; ICV, internal cerebral vein; P, posterior; and SS, straight sinus.
