A 74-year-old man with vasculopathic risk factors presented to the emergency room with a chief complaint of peripheral vision loss resulting from an intracranial hemorrhage in his right parietal and occipital lobes. Urgent craniotomy and ventriculostomy led to a stable clinical condition with subsequent development of a crossed quadrant homonymous hemianopsia (checkerboard visual field) due to a new right parieto-occipital infarct superimposed on a prior left occipital infarct. This uncommon visual field defect represents juxtaposed homonymous quadrantanopias that produce a striking checkerboard appearance that is almost pathognomonic for bilateral occipital lesions.
