The preservation or recurrence of images in the visual field after removal of the real stimulus is called 'palinopsia' or 'visual perseveration' which can be split up into three different types according to the latency between the real external stimulus and its apparent recurrence. For a long time it was subject of discussion whether the delusion is a sign of lacking cortical inhibition or of a cortical afterimage or part of an epileptic seizure. If there are different reasons for the three sorts of visual perseveration has not been answered yet. In our case report, however, it is possible to demonstrate a patient's posttraumatic lateralized long-latency visual perseveration for the first time as a clear-cut focal epileptic seizure which is approved by synchronous temporo-parietal epileptic discharges in the electroencephalogram.
在真实刺激移除后视野中图像的保留或重现被称为“视觉滞留”或“视觉后像”，根据真实外部刺激与其明显重现之间的潜伏期，可将其分为三种不同类型。长期以来，这种错觉是皮质抑制缺乏的迹象、皮质后像还是癫痫发作的一部分一直是讨论的主题。这三种视觉后像是否存在不同原因尚未得到解答。然而，在我们的病例报告中，首次有可能证明一名患者创伤后单侧化长潜伏期视觉后像是一种明确的局灶性癫痫发作，脑电图中的同步颞顶叶癫痫放电证实了这一点。
