Intermittent visual field defects caused by a dilated Virchow–Robin space close to the optic radiation: Therapeutic and pathomechanical considerations

Abstract

Dilated VRSs can cause a variety of neurological deficits depending on their size and location. Therefore, patients harboring dilated VRS should undergo early close inspection and in case of progressive neurological deficits, an operative therapy should be done; as valve mechanisms can cause a reduction of size when brain scans are conducted and later lead to occurrence of severe neurological deficits during phase of dilation.
