Recovery of cerebellar peduncle injury in a patient with a cerebellar tumor：validation by diffusion tensor tractography

The cerebellum has a complex network and relates to various clinical functions including ataxia, gait disturbance, hearing and vision, cognition and affective control. Cerebellar peduncles are the structure connecting the cerebellum to the brain stem and the cerebrum. There exist three cerebellar peduncles. The superior cerebellar peduncle （SCP） involves vestibular sense and proprio- ception connecting to the thalamocortical pathway. The middle cerebellar peduncle （MCP） is the largest structure among the three cerebellar peduncles conveying impulses from the cerebral cortex to the cerebellum through corticopontocerebellar tract.
