Polyopia is one of rare, visual hallucinations. A 61-year-old man suffered from daily episodes of polyopia and generalized convulsions, and he was diagnosed as right temporal lobe epilepsy. MRI revealed right amygdalar swelling. FDG-PET showed hypometabolism in the right anterior temporal and the mesial occipital areas. Polyopia is thought to be caused by dysfunction of updating process of visual information in the visual association cortices. It was most likely that, in this patient, both mesial temporal and ipsilateral occipital areas were responsible for manifesting epileptic polyopia, as ictal onset zone and symptomatogenic zone, respectively.
复视是一种罕见的视幻觉。一名61岁男性每天发作复视和全身性惊厥，被诊断为右侧颞叶癫痫。磁共振成像（MRI）显示右侧杏仁核肿胀。氟代脱氧葡萄糖正电子发射断层扫描（FDG-PET）显示右侧颞叶前部和枕叶内侧区域代谢减低。复视被认为是由视觉联合皮质中视觉信息更新过程功能障碍引起的。在该患者中，最有可能的是，内侧颞叶和同侧枕叶区域分别作为发作起始区和症状发生区，导致癫痫性复视的出现。
