Single photon emission computed tomography in a patient with unilateral auditory hallucinations

Abstract

We report a patient with right unilateral auditory hallucinations in association with right-sided hearing loss and tinnitus, a degree of anxiety and depression leading to self-poisoning, and delusional elaboration of the sensory experiences. Poor performance in visuospatial neuropsychological tests sensitive to frontal lobe damage, and poor performance on a visuospatial recognition memory test at 12 s delay were associated with a relative reduction of regional cerebral tracer uptake in mainly right anterior cingulate and right posterior temporal cortex.
