Fig 9. — Clinical examples show involvement of the inferior occipitofrontal fasciculus at coronal MR planes corresponding to those in Figure 6.

A, Enhanced T1-weighted image in a 58-year old man with a recurrent glioblastoma multiforme. This image is at the level of the frontal horn of the lateral ventricle, and the amygdala (A). Comparison with Figure 6A demonstrates that the enhanced tumor is spreading out of the temporal lobe via the region of the uncinate fasciculus (large arrows). The nonenhanced edema and tumor in the extreme and external capsules, around the claustrum (arrowhead), involve the region of the inferior occipitofrontal fasciculus (small arrows). This combined involvement of the uncinate fasciculus and the inferior occipitofrontal fasciculus may vary depending on the exact location of the upper margin of the uncinate fasciculus and the lower margin of the inferior occipitofrontal fasciculus and the angulation of the section.

B, Proton density–weighted image in a 52-year-old man with a temporal lobe astrocytoma spreading into the extreme and external capsules at the posterior amygdala/hippocampal head level. Comparison with Figure 6B shows that the tumor and edema is spreading out of the temporal lobe via the region of both the uncinate fasciculus (large arrows) and the inferior occipitofrontal fasciculus (small arrows).

C, T2-weighted image in a 36-year-old woman with a temporal lobe astrocytoma spreading into the extreme and external capsules. The tumor is at the level of the body of the lateral ventricle and hippocampus. Comparison with Figure 6C, obtained at a similar coronal plane, demonstrates that the tumor and edema are spreading out of the temporal lobe via the region of the inferior occipitofrontal fasciculus (arrows).

D, T2-weighted image in a 68-year-old woman with a temporal lobe anaplastic oligodendroglioma spreading into the deep white matter lateral to the thalamus. Comparison with Figure 6D demonstrates that the inferior occipitofrontal fasciculus (arrows) is involved in the tumor and edema spread out of the temporal lobe.
