[EEG recordings during episodes of palinacousis and palinopsia]

Palinopsia (visual perseveration) and palinacousis (auditory perseveration) are reported in a 51-year-old woman with a left temporo parietal astrocytoma. EEG showed a left temporal delta-focus with sharp waves. EEG was not modified during neither palinacousis nor palinopsia. The relationship between the two hallucinatory phenomena and epilepsy is discussed.
