Peduncular hallucinations following subarachnoid haemorrhage.
We describe the case of a 56-year-old woman who suffered vivid visual hallucination following subarachnoid haemorrhage (SAH). These occurred from day 9 to day 28 after the haemorrhage. An association with sleep disturbance, clinical findings, and the nature of the hallucinations suggested peduncular hallucinosis. Putative mechanisms in this case are discussed.
