A 53-year-old woman was found to have a left inferior homonymous quadrantanopia. Brain MRI disclosed a giant Virchow–Robin space compressing the right optic tract. After fenestration of this cystic lesion, most of the visual field loss resolved. Giant Virchow–Robin spaces may cause homonymous field defects which, with appropriate management, may improve.
