title: Palinopsia: cerebral localization with computed tomography.
abstract: We report three patients whose vivid visual experiences were initially attributed to psychiatric or metabolic derangements, in the absence of obvious neurologic findings. Each depicted repetitive visual images of previously viewed objects or scenes, not necessarily confined to the region of homonymous visual deficit. Each patient had a large occipital lobe lesion, well demonstrated by computed tomography. An important diagnostic clue was documentation that the portrayed images had actually been viewed recently and therefore represented visual transpositions in time or space.
