Peduncular Hallucinosis: An Unusual Case of Visual Hallucination in a Delirious Patient

Krishnendu Ghosh, Guitelle St. Victor


Visual hallucination is very common in case of delirium and other neuropsychiatric disorders. It is one of the most common clinical symptoms for which psychiatric consultation is requested on medical floors. When hallucination dominates the clinical presentation, a patient may be misdiagnosed as suffering from a psychiatric disorder. This case is a wonderful example of Peduncular Hallucinosis, an underlying organic pathology. A possible pontine tumor was discovered in a patient admitted to the medical floor with altered mental status in the absence of any focal neurological signs.
