Tumor disruption of WM tracts was observed in glioblastoma multiforme, which terminated fibers crossing the corpus callosum. In meningioma, DTT illustrated bulk displacement of the corticospinal tract in the affected hemisphere as well as preservation of the deviated axons. In anaplastic astrocytoma, fiber tracking demonstrated disruption of WM tracts at the tumor origin as well as intact axons through areas of tumor infiltration.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100005801_abs4\"><jats:title>Conclusions:<\/jats:title><jats:p>Fiber tracking results correlated with the clinical and histopathological features of the tumor.
