Management of hallucinations in patients with Parkinson disease is a challenge for both the physician and the patient. They occur in more than 30% of patients and they present mostly as visual hallucinations but other forms such as auditory and tactile hallucinations have been reported. We have reported an interesting patient with olfactory hallucinations and visual hallucinations. To our knowledge, olfactory hallucinations have been rarely described in patients with Parkinson's disease and might be added to the late complications of Parkinson's disease.
