Palinopsia refers to the persistence or reoccurrence of visual images after the stimulus has been removed from the visual field[^1]. Palinopsia can occur with or without deficits in the visual field.

Etiology

Palinopsia is typically attributed to a lesion in the non-dominant occipitotemporal cortex. Most cases of palinopsia due to occipital lesions are associated with a visual field defect[^2].

Examples of possible causes for palinopsia include:

Stroke[^3]
Infectious causes, such as in the context of an abscess[^4]
Epileptic[^5]
brain tumors[^6]
traumatic brain injury[^1]
