Auditory illusions caused by a small lesion in the right medial geniculate body.
Although the medial geniculate body (MGB) is a well-known integration center for the central auditory pathways, auditory symptoms caused by MGB damage have not been described. We report the appearance of the auditory illusions of hyperacusis and palinacousis in a 49-year-old man without previous psychiatric or epileptic illness after a small hemorrhagic infarction located mainly in the right MGB.
