Brainstem auditory hallucinosis

Abstract

We studied three patients with findings suggesting that auditory hallucinations may occur with lesions of the tegmentum of the pons and lower midbrain. The evidence was clinical (indicating location of the lesion), radiologic (CT), pathologic in one case, and physiologic (affirming integrity of the cochleas and auditory nerves). The condition is comparable with the Lhermitte peduncular-diencephalic visual hallucinosis.
