title: The role of visually evoked potentials in the management of hemispheric arachnoid cyst compressing the posterior visual pathways.
abstract: We report a case of an occipital arachnoid cyst in an infant, managed on the basis of changes in visually evoked potentials (VEPs). A significant asymmetry of VEP responses prompted neurosurgical intervention, which improved visual behavior and electrical response to both pattern and flash stimuli.
