Probabilistic arcuate fasciculus (AF) tractography was computed in healthy controls (HC) and for a patient with a diffuse glioma, IDH 1 wild type left frontal lobe. Bilateral curvature mapping and along-tract DTI measures were evaluated, modelling surface geometry. In HC, hemispheric asymmetries in tract curvature showed a more lateral and inferior trajectory on the left, not measured for the patient’s left AF, medially dislocated. In HC, a left-lateralized asymmetries (higher FA and volume) was measured, and it was preserved for the patient. During pre-surgical evaluation, the proposed developed tractography analyses allowed a quantitative investigation of AF dislocation and microstructural integrity.
