Abstract

Posterior fossa syndrome (PFS) is a well-known sequela of midline posterior fossa tumor resection. Patients typically exhibit transient behavioral, motor, and oculomotor disturbances that resolve within a few weeks to several months after surgery. The underlying pathophysiology of PFS is not completely understood, but contemporary literature has implicated injury to the dentate nucleus and/or exiting dentatothalamocortical fiber bundles as a causative factor. The authors present a case of a young male who developed a delayed variant of PFS typified by motor deficits and demonstrated diffusion restriction in the ipsilateral superior cerebellar peduncle. Because the correlation between PFS and the superior cerebellar peduncle injury is poorly described in the literature, particularly with regard to relevant radiographic imaging, the authors of this report hope their findings will contribute to that insufficient body of evidence.
