- Abstract
Peduncular hallucinosis is usually caused by infarction of the mesencephalic portion of the brainstem, and is characterised by acute onset of vivid, colorful hallucinations often consisting of moving patterns, people or animals, which the patient is aware are unreal. Charles Bonnet's syndrome is a similar condition, caused by impaired version. Both syndromes may be explained by visual release phenomena caused by lesions in different parts of the visual system. The article consists in two case reports of peduncular hallocinosis and a review of partinent literature.
