Demonstration of recovery of a severely damaged corticospinal tract: A diffusion tensor tractography and transcranial magnetic stimulation follow-up study

Abstract

We demonstrated the recovery of a severely damaged corticospinal tract (CST) in a 45-year-old female patient with intracerebral hemorrhage using diffusion tensor tractography and transcranial magnetic stimulation. Two longitudinal evaluations were conducted. There was no evidence of a CST in the affected hemisphere on the first evaluation. However, we observed evidence of a CST on the second evaluation. It seems that the affected motor function was recovered through the recovery of the damaged CST.
