Corticospinal tractography as a prognosticator for motor improvement after brainstem cavernoma resection.

Given their highly eloquent location, surgical morbidity of brainstem cavernomas (BSCs) remain significant. Currently, there are no clinical factors or imaging techniques that can reliably predict post-operative motor improvement. Diffusion-tensor imaging (DTI) might have some prognostic value. We present a case supporting the use of DTI as predictor of motor recovery following brainstem surgery.
