Three cases whose ABRs were abnormal were studied auditory pathology in brain. Case 1 who showed wave I, II in the right and wave I-III in the left was demonstrated to have glioma in the right pons. Case 2 who showed wave I-III in the right and I, II in the left was demonstrated to have hemorrhagic infarction in the left pons and midbrain. Case 3 who showed wave I-IV in the right and wave I, II in the left was demonstrated to have glioma mainly in the left pons. These findings suggest that wave I, II can be elicited if unilateral cochlear nucleus is preserved for the stimulus side and wave I, II, III can be elicited if unilateral cochlear nucleus and superior olivary complex are preserved for the stimulus side.
