Elvis is back: musical hallucinations in a Parkinson disease patient.

Hallucinations are common among patients with Parkinson disease (PD). Hallucinations, typically transitory and occurring at night, are classically visual and occur in 30% of treated patients; auditory hallucinations are rare. A musical hallucination (MH) is a rare type of complex auditory hallucination reported in only six PD patients so far. To the best of our knowledge, we present the first reported case of a patient with Parkinson disease who experienced auditory and visual MH.
