Abstract
Palinopsia is defined as persistence or recurrence of a visual image when the stimulus is no longer present. The authors describe a female patient with a left tentorial meningioma who experienced recurrent visual images. Computed tomography revealed a well demarcated, high-density mass above the left side of the tentorium, but formal field testing revealed no visual field defect. The findings in this case suggest that the palinopsia may have been the result of disordered temporal synthesis of visual experiences.
