title: Accessing escalators: a central vestibular disorder after posterior fossa tumor removal.
abstract: About 20% of childhood tumors originate within the central nervous system. Progress in assessment and treatment of these lesions has led to improved survival rates. We describe a patient with a posterior fossa ependymoma who despite a remarkable recovery following treatment has been frustrated by difficulty in using escalators. Such symptom selectivity is explained by specific vertical visuomotor and high-frequency vestibular deficits disrupting the execution of this complex motor act.
