[Peduncular hallucinosis caused by a tumour in the right thalamus. A case study]

Peduncular hallucinations are vivid, complex visual hallucinations. They generally arise as a result of lesions in the midbrain. A 46-year-old man had peduncular hallucinations arising from a tumour in the right thalamus. The patient was not operated on for this tumour. The visual hallucinations were treated with psychiatric medications. This treatment reduced the patient's anxiety and visual hallucinations and he became better able to cope with his symptoms. Psychiatrists need to increase their knowledge with regard to the diagnosis and treatment of these symptoms.
