Tour 2: Next/Previous/Start: In this slice, note the dark line running just beneath the lining of the left lateral ventricle. This is the geniculocalcarine tract. Run the spatial movie (choose the "cine" button next to the sagittal) to see how this structure runs its course from the ventral thalumus to the medial occipital lobe. In contrast to this black line, note the high signal extending anteriorly in two branches, one into the ansa lenticularis, and the other into the cerebral peduncle. This represents extension of edema, perhaps mixed with infiltrating tumor along white matter tracts.
