Hallucinations are defined as sensory phenomena in the absence of external sensory stimuli. Auditory hallucinations have been shown to arise from many different intracranial lesions, but seizures manifesting as musical hallucinations triggered by unruptured intracranial aneurysms are rare. We present a case of persistent, episodic musical hallucinations associated with seizures that led to the discovery of 2 small intracranial aneurysms. Typical electroencephalographic findings for seizure activity were observed but resolved after surgical clipping of the aneurysms. Concomitantly, the patient's hallucinations resolved. The literature on musical hallucinations is reviewed.
